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

(AIPMT-2015)

Solution

The $P-V$ diagram of an ideal gas compressed

from its initial volume ${V_0}\,to\,\frac{{{V_0}}}{2}$ 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.
