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

  Options

  • Option A

    Compressing the gas through an adiabatic process will require more work to be done.

  • Option B

    Compressing the gas isothermally or adiabatically will require the same amount of work.

  • Option C

    In either case, work done on the gas during compression is the same.

  • Option D

    Compressing the gas isothermally will require more work to be done.
