Determination of water equivalent of calorimeter (K)

A thermos Flask of 100 ml capacity is filled with distilled water. System is heated via electric coil connected to constant voltage and current source. As the temperature rise of 1-2 degrees is noted, the power supply is switched off. The initial and final temperatures should be noted for calculation of the K, water equivalent of calorimeter.
