46. A perfect gas goes from state A to another state B by absorbing
8 x 105 J of heat and doing 6.5 x 105 J of external work. It is now transferred between the same two states in another process in which it absorbs 105J of heat. Then in the second process
(a) Work done on the gas is 0.5 x 105J
(b) Work done by gas is 0.5 x 105J
(c) Work done on gas is 0.5 x 105J
(d) Work done by gas is 0.5 x 105J
Ans. a
