Principle

Different amounts of hot and cold water are mixed. The hot water is always poured into a calorimeter containing cold water (room temperature). This has the following advantage: the cold water defines the temperature of the calorimeter; and since the hot water is poured in, the mix temperature is the largest value which is found in every case. The emergence of a mix temperature is first qualitatively explained. In the supplementary problem the equation for the mix temperature is given. The comparison of the calculated and measured values shows that the heat capacity of the calorimeter must still be considered.
