MCQ
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?
- AIsochoric
- ✓Isothermal
- CAdiabatic
- DIsobaric
✓
Answer
Correct option: B.
Isothermal
b
The $P-V$ diagram of an ideal gas compressed
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.
