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.

Match List $I$ with List $II$ :
| List $I$ | List $II$ |
| $A$ Isothermal Process | $I$ Work done by the gas decreases internal energy |
| $B$ Adiabatic Process | $II$ No change in internal energy |
| $C$ Isochoric Process | $III$ The heat absorbed goes partly to increase internal energy and partly to do work |
| $D$ Isobaric Process | $IV$ No work is done on or by the gas |
