4) 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:
-
Compressing the gas isothermally will require more work to be done.
-
Compressing the gas through adiabatic process will require more wore to be done.
-
Compressing the gas isothermally or adiabatically will require the same amount of work.
-
which of the case (whether compression through isothermal or through adiabatic process) requires more work will depend upon the atomicity of the gas.
