# Question

Equal amounts of heat are added to different quantities of copper and lead. The temperature of the copper increases by 5.0oC and the temperature of the lead by 10 oC.

(a) The lead has (1) a greater mass than the copper, (2) the same amount of mass as the copper, (3) less mass than the copper.

(b) Calculate the mass ratio of the lead to the copper to prove your answer to part (a).

Initially at 20 oC, 0.50 kg of aluminum and 0.50 kg of iron are heated to 100 oC. (a) The aluminum gains (1) more heat than the iron, (2) the same amount of heat as the iron, (3) less heat than the iron. Why? (b) Calculate ...At what average rate would heat have to be removed from 1.5 L of (a) Water and (b) Mercury to reduce the liquid’s temperature from 20oC to its freezing point in 3.0 min? We all have had the experience that a room full of people always feels warmer than when the room is empty. Ten people are in a 4.0 m x 6.0 m x 3.0 m room at 20oC. If each person gives off heat at a rate of about 100 W and ...How much heat is required to completely boil away 0.50 L of liquid nitrogen at - 196oC? (Take the density of liquid nitrogen to be 0.80 x 103 kg/m3.) Atypical person’s normal metabolic rate (the rate at which energy is consumed) is about 4 x 105 J/h, and the average food energy in a Big Mac is 600 Calories.
