WebHeat can be useec to do work. For example, a steam engine can use heat energy in steam to move pistons. However, heat is transferred to the surroundings and so the general entropy is increased. Some say that this release of heat will lead to the `heat death of the Universe', as there is no more general movement for the heat to go.

WebFor solids and liquids. cp = cv (1) The specific heat represents the amount of energy required to raise 1 kg of substance by 1oC (or 1 K), and can be thought of as the ability to absorb heat.
