Gas 'A' undergoes change from state 'X' to state 'Y'. In this process, the heat absorbed and work done by the gas is $\displaystyle 10$ J and $\displaystyle 18$ J respectively. Now gas is brought back to state 'X' by another process during which $\displaystyle 6$ J of heat is evolved. In the reverse process of 'Y' to 'X',
Official answer
From NTA’s final answer key for this paper.
(4)
$\displaystyle 14$ J of the work is done on the gas 'A' by the surrounding.
