In an isothermal process,$\Delta Q = 0$.

Vedclass · Answer

(D) In an isobaric process,the pressure remains constant,so $\Delta p = 0$. In an isochoric process,the volume remains constant,so the work done $\Delta W = p \Delta V = 0$. In an isothermal process,the temperature remains constant,so $\Delta T = 0$. However,in an isothermal process,heat is exchanged with the surroundings to keep the temperature constant,so $\Delta Q 
eq 0$. Therefore,the statement in option $D$ is incorrect because $\Delta Q = 0$ is the condition for an adiabatic process,not an isothermal process.

List-$I$	List-$II$
$(A)$ Isothermal	$(I)$ $\Delta W = 0$
$(B)$ Adiabatic	$(II)$ $\Delta Q = 0$
$(C)$ Isobaric	$(III)$ $\Delta U \neq 0$
$(D)$ Isochoric	$(IV)$ $\Delta U = 0$
