Need Help on Chemistry: Gases……please read.?

2 containers of volume 1 L, 298 K…one hols .10 mol of N2. and the other holds .10 mol of H2. the avg. KE of N2 is 6.2 x 10^-21 J. They exhibit ideal gas behavior.

How would i measure the average kinetic energy of molecules?

which has, N2 or H2 has the greater avg speed? Is it H2 because it is lighter?

And what change could be made that would decreas the avg. KE of the N2 molecules in the container?

lastly, if the volume of the container holding the H2 was decreased to .5 L at 298 K, what change would occur in 1. pressure 2. avg speed of the H2 molecules?

PLEASE help me on these…. I will pick a best answer! thanks.

Which of these examples is ironic?

Which of the following is an example of irony associated with the Pardoner’s Tale?

-The men found what they were looking for
-The two men toasted the successful murder of their friend with a bottle of wine that the friend brought for them.
-Of all the characters in The Canterbury Tales who should listen to and learn from the tale, the one who needs it the most is the Pardoner.

Stumped on the Canterbury Tales?

Hello… I am reading the Canterbury tales for an English class. I am trying to read the Pardoner’s tale right now bbut nothing seems to make sense to me! can anyone help me with these questions?
“The Pardoner’s Tale”
1.At the end of his tale, the Pardoner asks the host to be the first one to pay for relics from the Holy Land. What is ironic about the Pardoner asking this and how does the Host respond? (2 pts)
2.What does the rioters’ reaction to their discovery reveal about their outlook on life? (2 pts)
3.In this story, the narrator uses personification (a figure of speech in which human qualities are given to an object, animal, or idea) to describe which “character”? (1)
4.Review the description of the Pardoner in the Prologue and the historical information about Pardoners in the introduction material. In a paragraph, explain how this tale is fitting or not fitting for the Pardoner to tell. (4 pts)
5.Do you think the moral illustrated by the tale still has meaning today? Why or why not? (2 pts)
6. Irony is the contrast between expectation and reality. Irony can take several forms: verbal irony exists when a person says one thing while meaning another; situational irony exists when the outcome of a situation is the opposite of what someone expected; dramatic irony occurs when the audience or reader knows something that the characters do not know. In a short paragraph explain 3 examples of irony that are found in the story. Be specific and support your claims with textual examples. (9 pts)

How can I become the Reeve from Chaucer’s Canterbury Tales?

For my English class, we were assigned a project in which we become a character in Chaucer’s Canterbury Tales. I was assigned the Reeve, which is an estate manager. This project has two parts, and I am stumped on both and I am looking for some creative inspiration as help:

1) The first part of the project is to assume the character‘s identity. So, how can I dress up as the reeve (clothing, any props, etc)? What would be his personality?

2) Based off of my character‘s identity, I have to choose a current event and create a tale or fable based on the event. Since the Reeve is an estate manager, I was thinking about doing the housing market’s crisis, but I have no idea how I could make it into an interesting tale. Ideas would be great.

Thanks for your help and answers are appreciated!
Sorry, I forgot to include that this is based strictly off of the Prologue, not the entire book.

Thanks!

Which of these is true of the opening lines of the Canterbury Tales?

Which of the following is true of the opening lines of the Canterbury Tales?

The lines create a setting for later conflict between the major characters in the story.

The lines foreshadow coming stories by dropping hints of what will come.

The lines are not much more than a rough translation into English of the opening lines of Bocaccio’s Decameron.

The lines suggest that the regenerative powers of the sun and the rebirth of spring are a fitting setting for a pilgrimage.

The lines closely follow the Latin tradition of using a bucolic setting to introduce a satiric writing, or satura. Chaucer uses the form of satura to make a subtle attack on corrupt members of the church, following the ideals of the Roman poet Horace, who said, “Satura tota nostre est!”

What modern day person that is known by almost anyone can be compared to a character of the Canterbury Tales?

I have a project which is due in 2 days, and I have no idea who to do it on. The guideline says:

“Choose any pilgrim from the Canterbury Tales. Choose one who has similarities to a modern person.
Focus on:
1. Explaining the pilgrim’s stereotype.
2. Comparing the stereotype to a modern one.
3. Deciding how understanding the stereotype defines the morals of our society.
4. Have the morals changed over time?”

I’m pretty much set to go, I just need a modern person to compare one of the pilgrims to. This modern person can’t be anyone, either. It has to be someone known by everyone.. Or someone everyone has heard of. For example, the president, Dick Chaney, Donald Trump, an actor/actresses, ect.

Can someone please help?

Canterbury Tales Fashion Show help character descriptions?

I need help i dont understand this character can u plz help me. the character is the doctor in the story and help me answer some questions about that character thnx.

Character: Doctor
Questions:
Complete view of the pilgrim, what the pilgrim’s personality is like, what he/she looks like, what possessions or accessories he/she carries.
What are the pilgrim’s facial features?
What type of clothes does the pilgrim wear?
What food does the pilgrim eat?
What type of work does the pilgrim do? (which is doctor my charact.)
How does the pilgrim contrast with the typical image of his/her position?
Note significance of things Chaucer does not tell his audience.

This is the description of the doctor: copied from the line of our character in the story

A Doctor too emerged as we proceeded;
Progress reading.strategy
No one alive could talk as well as he did
On points of medicine and of surgery,
For, being grounded in astronomy,
He watched his patient’s favorable star
And, by his Natural Magic, knew what are
The lucky hours and planetary degrees
For making charms and magic effigies.
The cause of every malady you’d got
He knew, and whether dry, cold, moist or hot;
He knew their seat, their humor and condition.
He was a perfect practicing physician.
These causes being known for what they were,
He gave the man his medicine then and there.
All his apothecaries in a tribe
Were ready with the drugs he would prescribe,
And each made money from the other’s guile;
They had been friendly for a goodish while.
He was well-versed in Aesculapius too
And what Hippocrates and Rufus knew
And Dioscorides, now dead and gone,
Galen and Rhazes, Hali, Serapion,
Averroes, Avicenna, Constantine,
Scotch Bernard, John of Gaddesden, Gilbertine.
In his own diet he observed some measure;
There were no superfluities for pleasure,
Only digestives, nutritives and such.
He did not read the Bible very much.
In blood-red garments, slashed with bluish-gray
And lined with taffeta, he rode his way;
Yet he was rather close as to expenses
And kept the gold he won in pestilences.
Gold stimulates the heart, or so we’re told.
He therefore had a special love of gold.

Plz help me. i need to write a description or page about my character bcuz my partner need to act it and we both dont get what it is saying so plz help us. plz. and ill edit it to to make a page to read about my character and act what is said here about him.

The model description includes physical characteristics, as well as info about the type of person the pilgrim is and what the person does. it should capture any subtle irony suggested by Chaucer.
Dont know who that is. We havent read story yet but she is telling us to just read our character and discuss it. plz help. i dont understand.

What forms of energy are present in a bouncing ball?

Is kinetic, heat, and chemical the forms of energy present in the simulated silicon in the article? I’m having trouble understanding which energy forms they’re talking about.
They talk about the speed changing the properties of the ball, making it stop rebounding off the surface, and adhere to the surface instead.

If Traveling Very Fast, the Very Small Just Stick: http://www.nytimes.com/2008/09/02/science/02obsbounce.html?partner=rssnyt&emc=rss

— In the everyday world, the harder you throw something like a basketball against the floor, the higher it will bounce.

In the world of the very, very small, things bounce differently.

Traian Dumitrica, a professor of mechanical engineering at the University of Minnesota, and Mayur Suri, a graduate student, ran computer simulations to precisely calculate the bouncing behavior of a sphere a few billionths of a meter in diameter consisting of about 30,000 silicon atoms.

For speeds up to 2,700 miles per hour, the silicon nanosphere exhibited basketball-like behavior — the faster it hit the surface, the greater the rebound velocity.

But then, at slighter higher velocities, the rebound velocity suddenly dropped, and at 3,300 m.p.h., the simulated nanoball didn’t bounce at all. It stuck to the surface.

The reason is that the pressure of impact rearranged the chemical bonds of some of the silicon atoms, which then went through a second transition during the bounce.

The additional chemical bonds and generation of heat dissipated the kinetic energy, slowing the bounce. At high enough velocities, so much of the kinetic energy was dissipated that the adhesive forces of the surface caught the nanoball.

The findings appear in the August issue of Physical Review B. Other scientists have already used this phenomenon to avoid splattering when applying coatings of nanoparticle.

Should I cook saturated fats and eat unsaturated fats raw?

I was doing the usual nutritional research for my diet. I should mention I’m mostly interested in getting into shape, so concerns of what kinds of fat I’m consuming are not my highest priority, other than the not really difficult stay away from trans fats. (Though as I understand it, they think trans fats may contribute to obesity, and they even have a reasonably good idea of why that is. They just don’t have anything especially conclusive.) Really taking an interest in the kinds of fats I eat and their role in heart disease and such is more of a “why not?” sort of thing.

Nonetheless I was checking up on the different kinds of fats getting the usual saturated fats O.K, unsaturated fats better, trans fats very bad stuff, when I found a site. (I really can’t provide a link largely because I don’t even remembler how I found it in the first place.) This site said you should use your saturated fats for cooking, and keep your unsaturated fats raw. It didn’t say why. It could be that was for entirely culinary reasons, smoke points and such. But given the context, I thought maybe not.

The following mind you is wild speculation, which I’m actually hoping that maybe you can either just shoot down as erroneous right now, or maybe tell me if it is right. But, I figure saturated fats tend to break down a bit when they get the heat, which tends to unsaturate them, and -maybe- actually make them healthier. In the meantime unsaturated fats tend to hydrogenate when heated which tends to produce trans fats. Now still more hypothetically one can imagine that progression going all the way from saturated fats to trans fats. But, I figure to produce a siginificant amount of trans fats, when your starting fats are saturated, you’d have to cook your particular food item practically down to charcoal.

Of course one could counter-argue that hydrogenation occurs in a hydrogen rich environment, and one could expect saturated fats shedding their hydrogens to be a very hydrogen rich environment. I don’t know. It’s not like unsaturated fats wouldn’t also produce a hydrogen rich environment. This is mostly an issue of hydrogen migration, I guess. Even if it’s just hydrogen migrating from one side of a fatty acid chain to the other.

I have a serious Biology question?

Which of these is rich in unsaturated fats?
beef fat
butter
a fat that is solid at room temperature
lard
olive oil

Are You Aware Of “The Increase In Saturated Fat” That NEVER WAS!?

This is a small excerpt directly from Anthony Colpo “The Great Cholesterol Con”

The Increase In Saturated Fat That Never Was

Even after adjusting data for increased life expectancy, a substantial increase in coronary and overall heart disease mortality is still evident during the first half of the last century. Is this increase in any way due to an increase in saturated fat consumption?

Abslotluely not.

Take a good look at Figure 1c , which shows the consumption of various fats during the last century. Beginning in the 1920′s total fat consumption increased steadily, due entirely to the accerlating use of vegetable oils, shortenings , and margarines. The increasing popularity of these unsaturated fat – rich vegetable fats also explains the rise in polyunsaturated fat intake and monounsaturated fat intake.
