Question

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

Options

• In an adiabatic process, the system is insulated from the surroundings.

• In an isochoric process, the pressure remains constant.

• In an isothermal process, the temperature remains constant.

• In an adiabatic process, pv^γ = constant.

Answer 1

In an isochoric process, the pressure remains constant.

Explanation:

In an isochoric process, the volume remains constant, not the pressure. Pressure can change in this process. All other statements are correct: an adiabatic process has no heat exchange, an isothermal process keeps the temperature constant, and PV^γ = constant for an adiabatic process.
