Question

a) Write the expression for work done in irreversible isothermal expansion of ideal gas​

Answer 1

Explanation:

In calculating the work done in an isothermal irreversible process, why do we consider the external pressure only (using formula: Wext=PextdV) but not the internal pressure? When the system expands, the internal pressure does the positive work, but even in this scenario, we use the equation as mentioned above.
