1. Calculate the work (), heat (), and change in internal energy () for a system undergoing a reversible isochoric temperature change from 1 = 100 to 2 = 200.

2. Calculate the work (), heat (), and change in internal energy () for a system undergoing a reversible isothermal compression from 1 = 3.8 102 3/mol to 2 = 7.6 103 ol at = 200

3. Calculate the work (), heat (), and change in internal energy () for a system undergoing a reversible isobaric compression from 1 = 3.8 102 3/ol to 2 = 7.6 103 3/ mol at = 5 10^5Pa.
