Eighty grams of cold water initially at 20 oC is combined with some amount of hot water having an initial temperature of 80 oC. Afterward, the final temperature of the mixture stabilizes at 40 oC. Assume the heat is exchanged only between the hot and cold water only (so that there is no heat loss to the surroundings). The specific heat capcity of water is 1.0 cal/(g Co).

What was ΔT and Q for the hot water? ΔTH =

QH =

5)Eighty grams of cold water initially at 20 oC is combined with some hot iron nails having an initial temperature of 180 oC. Afterward, the final temperature of this mixture also stabilizes at 40 oC. The specific heat capacity of iron is 0.11 cal/(g Co).

    When you mix two substances that are initially at different temperatures, the hotter substance cools and the colder substance warms until they reach a common temperature. Then the substances are said to be in thermal equilibrium. For our purposes assume that the heat is exchanged only between the hot and cold materials and that no heat is lost to the surroundings. The specific heat capacity of water is 1.0 cal/(g Co) and the specific heat capacity of copper is 0.092...
