Copy each problem and write your solutions to whole sheet/s of pad paper. Follow the format in problem solving. (Due Feb 26, 2012, Monday)
1. Calorimetry/Heat If the price of electrical energy is P 11.00 per kilowatt-hour, what is the cost of using electrical energy to heat the water in swimming pool (12.0m x 9.00 m x 1.5 m) from 15 to 27 deg. C?
2. Phase Change. An aluminum can with a mass of 0.500 kg contains 0.130 kg of water at a temperature of 80.0 deg. C. A 0.150 kg of ice at -2.0 is dropped into the can. Find the final temperature of the mixture. Assume no heat loss to the surroundings. The specific heat capacities of aluminum, water, and ice are 9.00 x 10^2 J/kg.Cdeg. , 4186 J/kg.Cdeg. , and 2.00 x 10^3 J/kg.Cdeg. respectively. The latent heat of fusion of ice is 33.5 x 10^5 J/kg.
Hint: Q(water) + Q(aluminum) = Q(ice)
3. Thermal Expansion. A brass cylinder is initially 20.0 deg.C. At what temperature will its volume be 0.300% larger than it is at 20.0 deg.C. The coefficient of linear expansion of brass is Alpha(brass) - 2.0 x 10^5 /Cdeg. Note:Beta = 3Alpha
4. Conduction. One end of an insulated (to the environment) metal rod is maintained at 100 deg.C, and the other end is placed in an ice-water mixture. The bar has a length of 50.0 cm and a cross-section area of 0.800cm^2. the heat conducted by the rod melts 3.00 g of ice in 5.00 min. The latent heat of fusion of ice is 80cal/g. Calculate the thermal conductivity k of the metal.
5. Radiation. The supergiant star Betelgeuse has a surface temperature of about 2900 K and emits a radiant power of approximately 4.00 x 10^30 W. Assuming that Betelgeuse is a perfect emitter (e=1) and spherical, find its radius.
