Question

1. A hamster runs on a treadmill connected to a 250 g weight through a pulley. The running hamster does work by raising the weight by 1.32 m, and gives off 8.0 J of energy as heat. Ignoring friction and any other effects, and treating the hamster as a closed system, compute ΔU for the hamster.

2. Which would you expect to have the larger molar heat capacity, NO or NO2? Why?
