During his honeymoon in Switzerland, James Joule is said to have used a thermometer to measure the tempera- ture difference between the water at the top and at the bottom of a waterfall. Take the height of the waterfall to be Ah and the acceleration of gravity, g, to be 9.81 m s-2. Assuming that all the potential energy change mg Ah of a mass m of water is used to heat that water by the time it reaches the bottom, calculate the temperature differ- ence between the top and the bottom of a waterfall 100 meters high. Take the specific heat capacity of water to be 4.18 J K¯g.

In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction.A chunk of lead weighing 19.61 grams and originally at 97.01 °C is dropped into an insulated cup containing 82.14 grams of water at 21.79 °C.The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.61 J/°C.Using the accepted value for the specific heat of lead (See the References tool), calculate the final temperature of the water. Assume that no heat is lost to the surroundings.

A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy available from foods. Since the "bomb" itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter. In the laboratory a student burns a 0.508-g sample of benzil (C14H1002) in a bomb calorimeter containing 1060. g water. The temperature increases from 24.70 °C to 27.80 °C. The specific heat capacity of water is 4.184 J gl°C1. The combustion enthalpy is -6784 k]/mol benzil. C14H1002(s) + 31/2 02(g) →14 CO2(g) + 5 H20(I) A,H° = -6784 kJ/mol %3D Calculate the heat capacity of the calorimeter. heat capacity of calorimeter = J/C
