The quanity of heat required to change the temperature of a substance depends of: the magnitude of the temperature change, the amount of substance, the type of substance. Calories (cal): the quanity of heat required to change the temperature of one gam of water by one degree celcius: food calories are diferent. Heat capacity (c): the quanity of heat required to change the temperature of an object or substance by one degree. Speciic heat calacity (c): the heat capacity per gram of substance. The magnitude of the temperature change (delta t) Law of conservaion o energy: energy can neither be created or destroyed in ordinary processes. Total energy is an isolated system must remain constant. In interacions between and system and its surroundings, the total energy remains constant.
