NEET Physics Question - Thermal Physics

In thermodynamic processes which of the following statements is not true? (2009)

In an isochoric process pressure remains constant

In an isothermal process the temperature remains constant

In an adiabatic process $PV^\gamma = \text{constant}$

In an adiabatic process the system is insulated from the surroundings

An isochoric process is one in which volume remains constant, not pressure. Therefore, statement (a) is incorrect.
