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

  case which requires (whether compression through isothermal or through adiabatic process) more work will depend upon the atomicity of the gas.
