Isothermal reversible systems

Postby EmmaShahabi1L » Thu Jan 26, 2017 2:02 pm

Which equation would we use to calculate the work for an isothermal reversible process? For this question we know only the initial and final volumes, the initial pressure and initial temperature.

We use w = -nRTln (V2/V1). This is the equation we use for work at variable pressure.

And this equation works because isothermal means that the temperature stays constant, thus we don't need an initial and final temperatures, the initial temp will do.
