Question

In thermodynamic processes, which of the following statements is not true? 

(a) In an isochoric process pressure remains constant 

(b) In an isothermal process the temperature remains constant 

(c) In an adiabatic process PVg = constant 

(d) In an adiabatic process the system is insulated from the surroundings

Answer 1

Correct option: (a) In an isochoric process pressure remains constant

Explanation:

In an isochoric process volume remains constant whereas pressure remains constant in isobaric process.
