Gas 'A' undergoes change from state 'X' to state 'Y'. In this process, the heat absorbed and work done by the gas is 10 J and 18 J respectively. Now gas is brought back to state 'X' by another process during which 6 J of heat is evolved. In the reverse process of 'Y' to 'X',
  1. (1)1818 J of the work is done by the gas 'A'.
  2. (2)22 J of the work is done by the gas 'A'.
  3. (3)1212 J of the work is done on the gas 'A' by the surrounding.
