Question

An ideal gas is compressed to half its initial volume by means of several processes. Which of the process results in the maximum work done on the gas?

(a) Isochoric

(b) Isothermal

(c) Adiabatic

(d) Isobaric

Answer 1

Correct option (c) Adiabatic

Explanation:

The P -V diagram of an ideal gas compressed from its initial volume V₀  to V₀/2 by several processes is shown in the figure.

Work done on the gas : Area under P-V curve As area under the P-V curve is maximum for adiabatic process, so work done on the gas is maximum for adiabatic process.
