Calculate ΔU of a gas for a process in which the gas absorbs 45 J of heat and does 11 J of work by expanding.

Question

Quizplus · Accepted Answer

The change in internal energy (ΔU) of a gas can be calculated using the first law of thermodynamics, which is ΔU = Q - W, where Q is the heat absorbed by the system and W is the work done by the system. Here, Q = 45 J (heat absorbed) and W = 11 J (work done by the system). Thus, ΔU = 45 J - 11 J = 34 J.
