Questions  

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 will require more work to be done.
b
compressing the gas through adiabatic process will require more work to be done.
c
compressing the gas isothermally or adiabatically will require the same amount of work.
d
which of the case (whether compression through isothermal or through adiabatic process) requires more work will depend upon the atomicity of the gas.

detailed solution

Correct option is B

Wext=negative of area with volume-axis      W(adiabativ)>W(isothermal)
