An Intiative by Sri Chaitanya

The amount of heat supplied in path AC is 200 J, then the internal energy of gas at ‘C’ is 150 J.

The amount of heat supplied in path AC is 200 J, then the internal energy of gas at ‘C’ is 75 J.

If the internal energy of gas at state B is 20 J. Then the amount of heat supplied to the gas to go from A to B may be 5 Joule.

If the internal energy of gas at state B is 20 J. Then the amount of heat supplied to the gas to go from A to B must be 10 Joule.

answer is A.
