	Calorimeter - Wikipedia, the free encyclopedia
		The word calorimeter is derived from the Latin word calor, meaning heat.
		Any microcalorimeter must have a low-heat-capacity mass to absorb incident X-ray photons, a weak link to a low-temperature heat sink which provides the thermal isolation needed for a temperature rise to occur, and a thermometer to measure change in temperature.
		In particle physics, a calorimeter is a component of a detector that measures the energy of entering particles.

	AllRefer.com - calorimetry (Physics) - Encyclopedia
		The measurement given by the most common type of calorimeter depends upon the temperature change in a fixed quantity of water (or some other liquid whose heat capacity is known) when heat is transferred between the water and an exothermic or endothermic process.
		The accuracy of this method of heat measurement depends on the assumption that all the heat transferred in the process passes into or out of the water in which the temperature change is measured, no heat being lost to the environment and none being absorbed by the walls of the container.
		Calorimeters are also employed to measure the energies of elementary particles.
