A perfect gas goes from state A to stale B by absorbing \[8\times {{10}^{5}}\,J\] of heat and doing \[6.5\,\times {{10}^{5}}J\] of external work. It is now transferred between the same two states in another process in which it absorbs \[{{10}^{5}}J\]  heat. In the second process

A) work done on gas is \[{{10}^{5}}J\]

B) work done on gas is \[0.5\,\times {{10}^{5}}\,J\]

C) work done by gas is \[{{10}^{5}}J\]

D) work done by gas is \[0.5\times {{10}^{5}}J\]
