In: 6 Answers ActiveNewestOldest Anonymous Posted December 27, 2019 0 Comments Compressing air makes it hot, compress it a lot and it gets very hot. Take some energy away to bring it to room temperature. In reverse, expanding air makes it cold, we took away the heat earlier, so it has to take heat from the surroundings.
