This is due to an … WebIt means adding heat. Under this circumstance, all positive temperature systems increase their entropy, and all negative temperature systems decrease it. For black holes, heating reduces the temperature (negative specific heat) but increases the entropy, as always. This is definition of temperature. – Ron Maimon.
