Q2.3 Solar houses are designed to retain the heat absorbed during the day so that the stored hear can be released during the night. A botanist produces steam at 100- during the day and then allows the steam to cool to 0 °C and freeze during the night. How many kilograms of water are needed to store 200 kJ of energy for the process? (Use the laten heat of vaporization of water L. = 22.6 × 105 J/ Kg, the laten heat of fusion of water Lr= 33.5 x 104 J/Kg, and the specific heat capacity of water c = 4186 J/kg. C. Hint: you need to use both the formula of the heat Q = mcVT and Q = mL)

Rubbing your hands together warms them by converting work into thermal energy. If a woman rubs her hands back and forth for a total of 20 rubs, at a distance of 7.50 cm per rub, and with an average frictional force of 40.0 N, what is the temperature increase? The mass of tissues warmed is only 0.100 kg mostly in the palms and fingers. Your answer must have three significant figures and the temperature change in centigrade.

Digestingfat produces 9.3 food calories per gram of fat, and typically 80%of this energy goes to heat when metabolized. (One food calorie is1000 calories and therefore equals 4186 J.) The body then movesall this heat to the surface by a combination of thermal conductivityand motion of the blood. The internal temperature of the body(where digestion occurs) is normally 37C, and the surface is usuallyabout 30C. By how much do the digestion and metabolism of a2.50 g pat of butter change your body’s entropy? Does it increase ordecrease?
A room is lighted by four 100 W incandescent lightbulbs. (The power of 100 W is the rate at which a bulb converts electrical energy to heat and the energy of visible light.) Assuming that 73% of the energy is converted to heat, how much heat does the room receive in 6.9 h?

A-2.16. The heat capacity of air is much lower than the heat capacityof water and a relatively small amount of heat is sufficient to change its temperature. Is itone of the reasons why in deserts, despite the high temperature during the day, wit is bitter cold at night. Heat capacity of air in constant volume wroom temperature is approximately 21 J K-1 mol-1. How much heat is needed toIncrease the air temperature in a room of 5.5 mx 6.5 mx 3.0 m by 10 ° C? Howa 1.0 kW heater would have to be on for a long time to achieve this temperature change,if there was no heat loss
Radioactive decay of granite and other rocks in Earths interior provides sufficient energy to keep the inrerior molten, to heat lava, and to provide warmth to natural hot springs.This is due to the average release of about 0.03 J per kilogram each year. Find an increase in temperature for a thermally insulated chunk of granite that takes about 13.2 million years to change temperature. (Assume that the specific heat capacity c of granite is 800 J/kg. C. Use the equation Q=cmdeltaT.
