In the thermodynamic processes, which of the following statements is NOT true? (a) In an isothermal process, the temperature remains constant. (b) In an adiabatic process, the system is insulated from surroundings. (c) In an isochoric process, pressure remains constant. (d) In an adiabatic process, PVγ = constant.

Answer: (c). (a), (b), (d) are correct definitions/relations. In an isochoric process the volume is constant, not the pressure. So the answer is (c).
