Relationship btw volume and temperature of an ideal gas

[n.hirsch1]

Homework Statement

The is a piston the is massless and moves with friction
A) assuming that out gas is ideal, we will get v = constant T. What are your variables in this case?
B) If you plot V vs T on a graph, what is the slop of your graph?
C) What is the number of moles for this gas?
D) Using the numbers of moles and slope, determine pressure.

Homework Equations

PV = nRT?

The Attempt at a Solution

Once again, this is from my physics TA and I have no clue how to approach it. The only thing I could think of is that he is implying that we are supposed to use PV = nRT, since then v is directly proportionate to T. I am not sure how to use this to determine the number of moles, unless I am supposed to assume 1?
I guess my question is how would you approach this? I am not really sure what it is asking for.

The way you have worded things is rather confusing. For example,

"The is a piston the is massless and moves with friction"​

makes very little sense.

Okay, I understand that there is some gas inside a piston. And there is friction? Or did you mean to say frictionless?

I think you'll have to explain/write the problem more carefully, and proofread the spelling and grammar. If you spot errors after submitting a post, please edit it with corrections.
