From the first law of thermodynamics, the work done is -36 J.

What is the work done?

We are told that the gas is expanding hence it does work while heat is absorbed from the surroundings. This implies that q is positive while w is negative.

Hence;

U = q - w

w = q - U

w = 89J - 125J

w = -36 J
