WebHeat is a form of energy. Heat flows from hot objects to cool objects. It flows from one object to another because of their difference in temperature. The cool object absorbs the energy and becomes warmer. Objects are … WebThis phenomenon is explained by the second law of thermodynamics, which relies on a concept known as entropy. Entropy is a measure of the disorder of a system. Entropy also describes how much energy is not available to do work. The more disordered a system and higher the entropy, the less of a system's energy is available to do work. domino\\u0027s pizza kingman az
