AI Thread Summary
The discussion revolves around a thermodynamics problem from Zemansky, specifically focusing on a quasi-static process involving a gas in a cylinder. The key equation used is W=-∫PdV, which relates work done to changes in volume. Participants note the lack of clarity regarding the initial volume (Vo) and emphasize the assumption that the gas temperature remains constant throughout the process. Additionally, it is highlighted that the final pressure of the gas must equilibrate with the pressure in the cylinder. Overall, the conversation underscores the importance of defining initial conditions and assumptions in thermodynamic problems.

Homework Equations


$$W=-\int PdV$$

The Attempt at a Solution


The gas fills the cylinder slowly and any increase in pressure of system is countered by the upward motion of piston. So the process is quasi-static.
But how do I find final amount of gas in the cylinder?

You did not show the complete problem. Vo is not even defined.
 
Oops.

They apparently expect you to assume that the temperature of the gas does not change during the process, and that even the gas in the original container equilibrates with the temperature of the surrounding air. They also expect you to assume that the final pressure of the gas in the container equilibrates with the pressure of the gas in the cylinder.

Thread 'Errors and significant figures'

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'

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...
