Physics Thermodynamics NEET Previous Year Question MCQ (Single Correct)

A gas is compressed isothermally to half its initial volume. The same gas is compressed separately through an adiabatic process until its volume is again reduced to half. Then

A
Compressing the gas isothermally or adiabatically will require the same amount of work.
B
Which of the case (whether compression through isothermal or through adiabatic process) requires more work will depend upon the atomicity of the gas.
C
Compressing the gas isothermally will require more work to be done.
D
Compressing the gas through adiabatic process will require more work to be done.

Text Solution

Verified by Experts
The correct answer is:
D

On P-V diagram,

Area under adiabatic curve > Area under isothermal curve. So compressing the gas through adiabatic process will require more work to be done.
