Concept Introduction:

Law of conservation of energy states that total energy of an isolated system remains constant, energy remains conserved overtime. This is first law of thermodynamics.

Quantity of heat exchanged in an experiment is dependent on 3 factors-amounts of materials, specific heat capacity and the temperature change the material undergoes. The general relationship is as follows:

  heat=(mass)(specificheat)(changeintemeprature)
