(B) The heat energy absorbed by a system is given by the first law of thermodynamics: $\Delta Q = \Delta U + W$.For the heat energy absorbed $\Delta Q$ to be equal to the work done $W$ (which is the area under the $PV$ graph),the change in internal energy $\Delta U$ must be zero.Since the internal energy of an ideal gas depends only on its temperature $(\Delta U = nC_v\Delta T)$,$\Delta U = 0$ implies that the temperature remains constant $(\Delta T = 0)$.Therefore,this condition is satisfied during an isothermal process.

During which of the following thermodynamic processes represented by a $PV$ diagram can the heat energy absorbed by the system be equal to the area under the $PV$ graph?
