Irreversible Adiabatic Expansion And Compression

One mole of a...

Question

One mole of an ideal gas is expanded from a volume of $3 L$ to $5 L$ under a constant pressure of $1 a t m$ . Calculate the work done by the gas.

Solution

Irreversible process.
$\begin{matrix} W = - P_{e x t} (v_{2} - v_{1}) \Rightarrow - 1 (5 - 3) \Rightarrow - 2 L a t m W = - 2 L a t m \end{matrix}$
