The thermodynamic process, in which internal energy of the system remains constant is

Step-by-step solution

An isothermal process is a thermodynamic process in which the temperature of a system remains constant. The transfer of heat into or out of the system happens so slowly that thermal equilibrium is maintained. Δ T = 0 ,   Δ U = n C V ∆ T = 0 . According to first law of thermodynamics, ∆ Q = ∆ U + ∆ W ⇒ ∆ Q = ∆ W
