If Q is the heat liberated from the system and W is the work done on the system then first law of thermodynamics can be written as,

(A)Q = - W
(B)Q = -W
(C)Q = + W
(D)Q = W - Correct

Answer: (D)

Solution

The first law is with the heat absorbed by the system and the work done on the system. Here heat liberated from the system is , so heat absorbed is . Then $Δ
