Question

The work done by a gas is maximum when it expands from a volume \( V_1 \) to \( V_2 \), then the expansion is

• A. Isothermal expansion
• B. Adiabatic expansion
• C. Isobaric expansion
• D. Free expansion

Hint:

The work done is maximized in an adiabatic expansion because no energy is lost as heat, all energy goes into doing work.

Answer 1

The Correct Option is B

The work done by the gas during an expansion is maximum in an adiabatic process. In an adiabatic process, there is no heat exchange with the surroundings, and all the energy change goes into doing work, which maximizes the work done. Thus, the correct answer is: \[ \boxed{\text{Adiabatic expansion}} \]
