Description

To determine the specific evaporation heat QV of water, pure steam is fed into the calorimeter in the experiment P2.4.1.3, in which cold water is heated to the mixing temperature ϑm. The steam condenses to water and gives off heat in the process; the condensed water is cooled to the mixing temperature. The experiment measures the starting temperature ϑ2 and the mass m2 of the cold water, the mixing temperature ϑm and the total mass

By comparing the amount of heat given off and absorbed, we can derive the equation
