Cycles in a heat engine The basic idea of a heat engine is to
add heat to a gas, and have the gas perform work on its environment
via an expansion, which in turn is used to power motion. The gas is
then restored to its original temperature and the cycle begins
again. You can assume that the same amount of gas remains in the
engine during the cycle. A convenient way to think about these
cycles is a pressure...
