Homework Help Overview

The discussion revolves around the working gas problem described by the equation pv = nRt, focusing on the implications of work done during a gas process, particularly in the context of an isobaric process.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants are questioning the implications of the problem statement regarding work done, with some asserting that the answer cannot be zero and others exploring the definition of work in the context of gas expansion.

Discussion Status

The discussion is active, with participants expressing differing views on the nature of the work done and its implications for the problem. Some guidance has been offered regarding the definition of work in isobaric processes, but no consensus has been reached.

Contextual Notes

Participants are navigating potential misunderstandings about the problem's parameters, including the stated amount of work and the conditions of the gas process.

Homework Equations



pv = nRt

The Attempt at a Solution


The answer is zero because it does not move since no work is being done.
 
Physics news on Phys.org
Doesn't the volume change?
 
This is pretty disturbing. Firstly, the problem says "this process is8000 J.". Secondly, no, the answer is not zero. I am quite confident about that.
 
Okay since we know it not zero then if 8000 work is being done than is the problem reiterating the work that was done so A?
 
Show us your work.

From where did you get this problem (please tell me)? I don't want to buy the book by accident.

No, it's not A. How is work defined when gas expands? In this case the process is isobaric meaning pressure is constant.
