Abstract: A new method which measures specific heat of water with a constant flow calorimeter is reported. When the steady state is established, the amount of heat generated by the current in the wire equals that received by the passing water and lost to the surroundings. Two separate experiments eliminated the unknown factor of the heat lost to the surroundings. The accuracy of the experimentresult is rising up notably.

Key words: specific heat capacity, constant flow calorimeter, constant head of water apparatus, heat, the thermocouple
