A gas undergoes change from state A to state B. In this process, the heat absorbed and work done by the gas is 5 J and 8 J, respectively. Now gas is brought back to A by another process during which 3 J of heat is evolved. In this reverse process of B to A :

Question

A gas undergoes change from state A to state B. In this process, the heat absorbed and work done by the gas is 5 J and 8 J, respectively. Now gas is brought back to A by another process during which 3 J of heat is evolved. In this reverse process of B to A : (A) 10 J of the work will be done by the gas. (B) 6 J of the work will be done by the gas. (C) 10 J of the work will be done by the surrounding on gas. (D) 6 J of the work will be done by the surrounding on gas.

Correct answer is (d) 6 J of the work will be done by the surrounding on gas.

Q. A gas undergoes change from state $A$ to state $B$ . In this process, the heat absorbed and work done by the gas is $5 J$ and $8 J$ , respectively. Now gas is brought back to $A$ by another process during which $3 J$ of heat is evolved. In this reverse process of $B$ to $A$ :

$10 J$ of the work will be done by the gas.

$6 J$ of the work will be done by the gas.

$10 J$ of the work will be done by the surrounding on gas.

$6 J$ of the work will be done by the surrounding on gas.

Correct answer is (d) $6 J$ of the work will be done by the surrounding on gas.
