\nThe principle of ‘heat lost = heat gained’ is the fundamental basis of calorimetry. Calorimetry is the science or act of measuring changes in state variables of a body for the purpose of deriving the heat transfer associated with changes of its state due to chemical reactions, physical changes, or phase transitions under specified constraints. In an isolated system, when substances at different temperatures come into contact, heat flows from the hotter substances to the colder substances until thermal equilibrium is reached. The total amount of heat energy lost by the hotter substances equals the total amount of heat energy gained by the colder substances.
\n<\/section>\n
\nThe principle of conservation of energy applied to heat transfer between objects in thermal contact is known as the principle of calorimetry.
\n<\/section>\n
\nThermal equilibrium is the state achieved when objects in contact have reached the same temperature and there is no net heat flow. Vaporization is a phase transition. The principle of colors relates to optics, not heat transfer.
