Web25 apr. 2016 · To part 1, a polytropic process assumes that during compression/expansion, the ratio of work being done to heat being transferred is a constant. One example is when air is compressed in an engine's cylinder. There is work being done on the gas, and as it heats up, it transfers heat out of the cylinder.
