Textbook Questions 3) The same heat transfer into identical masses of different substances produces different temperature changes. Calculate the final temperature when 1.00 kcal of heat transfers into 1.00 kg of the following, originally at 20.0"C: (a) water; (b) concrete; (c) steel; and (d) mercury. (a: 21.0 C; b: 25.0"C; c: 29.3"C; d: 50.0"C) 4) Suppose identical amounts of heat transfer into different masses of copper and water, causing identical changes in temperature. What is the ratio of the mass of copper to water? (10.8) 5) (a) The number of kilocalories in food is determined by calorimetry techniques in which the food is burned and the amount of heat transfer is measured. How many kilocalories per gram are there in a 5.00-g peanut if the energy from burning it is transferred to 0.500 kg of water held in a 0.100-kg aluminum cup, causing a 54.9"C temperature increase? (b) Compare your answer to labeling information found on a package of peanuts and comment on whether the values are consistent. (a: 5.73 kcal/g; b: -) 6) A bag containing ice is much more effective in absorbing energy than one containing the same amount of water. (a) How much heat transfer is necessary to raise the temperature of 0.800 kg of water from 0"C to 30.0"C? (b) How much heat transfer is required to first melt 0.800 kg of 0"C ice and then raise its temperature to 30.0"C? (c) Explain how your answer supports the contention that the ice is more effective. (a: 1.00*10* J; b: 3.68*105 J; c: -) 7) On a trip, you notice that a 3.50-kg bag of ice lasts an average of one day in your cooler. What is the average power in watts entering the ice if it starts at 0"C and completely melts to water in exactly one day? (13.5 W) 8) The energy released from condensation in thunderstorms can be very large. Calculate the energy released into the atmosphere for a small storm of radius 1 km, assuming that 1.0 cm of rain is precipitated uniformly over this area. (7*1013 J)
