- Homework Statement
- How do I find the volume-pressure equation for an expanding ideal gas for the figure below?

- Relevant Equations
- pV=nRT

There is no atmosphere pressure.

My work :

pA=k(x-x

But this should be false beccause I want to use W=∫PdV to find work done by the gas but my final anwer is wrong ...

Please guide me where my mistake is if you have enough time. Thanks.

_{0}) => pA=(k/A)(V-V_{0})But this should be false beccause I want to use W=∫PdV to find work done by the gas but my final anwer is wrong ...
