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

(8)
