Vedclass · Answer

(C) Free expansion is an adiabatic process where work done $W = 0$ and internal energy change $\Delta U = 0$. Because the process is rapid and uncontrolled, the system does not pass through a series of equilibrium states. Since a $p-V$ diagram requires the system to be in thermodynamic equilibrium at every point to define pressure and volume, free expansion cannot be plotted as a continuous path on a $p-V$ diagram. Therefore, the statement that free expansion can be plotted on a $p-V$ diagram is incorrect.

In case of free expansion, which one of the following statements is $\underline{\text{WRONG}}$?
