Reversible Expansion

[Bianca Barcelo 4I]

What exactly is reversible expansion? Also, how would you calculate the work of a gas that is reversibly expanding?

[Manu Vohra 1L]

The equation we use is :
A reversible process is a process whose direction can be "reversed" by inducing infinitesimal changes to some property of the system via its surroundings.

[Lorena Zhang 4E]

For example, the volume of the gas inside the container would not be fixed. It would increase/decrease depending on the pressure. We calculate the work of reversible expansion by using integral since the pressure keeps changing. The final equation would be w=-nRTln(V2/V1).

Something else to note is that this equation is only used when temperature is constant, because all the other q equations involve a delta T, whereas this one is just T by itself.
