WebPrinciple of calorimetry. The principle of calorimetry (or principle of mixtures) states that for an insulated system, heat energy lost by the hot body is equal to the heat energy gained by the cold body. m 1c 1(t 1−t)=m 2c 2(t−t 2) Note: Heat transfer occurs until both the bodies attain the same temperature ( t ). WebIn calorimetry experiments we measure heat transfer. Say we take a hot piece of metal and put it in some cold water, and measure the rise in temperature of t...
