When a volume of air is compressed
- heat is gained.
- no heat is lost or gained.
- heat is lost.
Explanation
Compressing a gas does work on it and raises its internal energy, so its temperature and heat content increase. This is why compressor discharge air is hot; an isothermal process (no temperature change) would require continuous heat removal, which does not occur in a turbine compressor.
