Relationship btw volume and temperature of an ideal gas

AI Thread Summary
The discussion revolves around understanding the relationship between volume and temperature of an ideal gas in a piston system. The key equations referenced include PV = nRT, indicating that volume is directly proportional to temperature when pressure is constant. Participants express confusion regarding the problem's wording and seek clarification on how to identify variables, determine the slope of a V vs T graph, and calculate the number of moles and pressure. The importance of clear communication in problem statements is emphasized, highlighting the need for proofreading to avoid misunderstandings. Overall, the thread focuses on the application of ideal gas laws and the need for precise language in physics problems.

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.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
