A gas goes from state 1 to state 2 along path I, doing 300 J of work, and along path II, doing 200 J of work. Its internal energy rises by 150 J. Find the difference in the heat absorbed, $Q_{I} - Q_{II}$ , in joules.

Answer:

100

Solution:

$Δ U$ is the same for both paths. $Q_{I} = 150 + 300 = 450$ J and $Q_{II} = 150 + 200 = 350$ J. The difference is 100 J.
