600 grams of boiling water (temperature 100 C, specific heat capacity 4.2 J/K/gram) are poured into an aluminum pan whose mass is 880 grams and initial temperature 29 C (the specific heat capacity of aluminum is 0.9 J/K/gram). After a short time, what is the temperature of the water? n = E o c What simplifying assumptions did you have to make? 3 Assume that energy diffuses throughout the pan and water so that all parts reach the same final temperature. 3 Assume negligible energy transfer between the surroundings and the system consisting of the pan plus the water. 3 Assume that the water temperature hardly changes. 3 Assume the specific heat capacity is nearly constant in this temperature range.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER In the Niagara Falls hydroelectric generating plant, the energy of falling water is converted into electricity. The height of the falls is about 50 meters. Assuming that the energy conversion is highly efficient, approximately how much energy is obtained from one kilogram of falling water? Therefore, approximately how many kilograms of water must go through the generators every second to produce a megawatt of power (106 watts)? :] kg/s Additional Materials
