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 $P{V}^{\gamma }=$ constant
• D. In an adiabatic process the system is insulated from the surroundings

Answer 1

Answer: (A)

In isochoric process, it is volume that is kept constant. If pressure is kept constant, it is an isobaric process.
