Heat and Thermodynamics question

2016 · Q155

NEETPhysicsHeat and ThermodynamicsMCQ+4 / −1
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
  1. A
    Compressing the gas isothermally or adiabatically will require the same amount of work.
  2. B
    Which of the case (whether compression through isothermal or through adiabatic process) requires more work will depend upon the atomicity of the gas.
  3. C
    Compressing the gas isothermally will require more work to be done.
  4. D
    Compressing the gas through adiabatic process will require more work to be done.

Correct answer: D

NEET 2016 Phase 1 Physics - Heat and Thermodynamics Question 77 English Explanation

V1 = V, V2 = V/2

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.
