Chapter 15, Problem 98RCQ
Heat added to a substance goes partly into the translational kinetic energy of its molecules, which directly elevates temperature. For some substances, large proportions of heat also go into vibrations and rotations of the molecules. Discuss whether you’d expect materials in which a lot of energy goes into nontranslational molecular motions to have a high or a low specific heat capacity.

Evaporation of sweat requires energy and thus take excess heat away from the body. Some of the water that you drink may eventually be converted into sweat and evaporate. If you drink a 20-ounce bottle of water that had been in the refrigerator at 3.8 °C, how much heat is needed to convert all of that water into sweat and then to vapor?? (Note: Your body temperature is 36.6 °C. For the purpose of solving this problem, assume that the thermal properties of sweat are the same as for water.)
a. 71.18 J
b. 81.17 J
c. 71.18 kJ
d. 81.17 kJ
A classroom that normally contains 40 people is to be air-conditioned with window air-conditioning units of 5-kW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 kJ/h. There are 10 lightbulbs in the room, each with a rating of 100 W. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 kJ/h. If the room air is to be maintained at a constant temperature of 21°C, determine the number of window air-conditioning units required.
Compute for the amount of heat that a 2.3-liter of sweat can remove from Joe's 70-kg body via evaporation. By how much will Joe's body temperature will rise if this amount of heat cannot be eliminated from his body? Specific heat value is 1 cal/g°C. Consider the sweat as purely water.

- Sweating is one of the main mechanisms with which the body dissipates heat. Sweat evaporates with a latent heat of 2 430 kJ/kg at body temperature, and the body can produce as much as 1.5 kg of sweat per hour. If sweating were the only heat dissipation mechanism, what would be the maximum sustainable metabolic rate, in watts, if 80% of the energy used by the body goes into waste heat?arrow_forwardSuppose you are trying to choose between two winter jackets. Suppose also that you have a heat-producing mannequin available for your use and you are able to adjust the mannequin’s rate of heat production. According to the equation: M = (1/I)(TB-TA) described in chapter 10, insulation is equal to (TB – TA)/M (this is in fact a general equation for insulation). How would you make a quantitative comparison of the insulation provided by the two jackets?arrow_forwardWhen energy shortages occur, magazine articles sometimes urge us to keep our homes at a constant temperature day and night to conserve fuel. They argue that when we turn down the heat at night, the walls, ceilings, and other areas cool off and must be reheated in the morning. So if we keep the temperature constant, these parts of the house will not cool off and will not have to be reheated. Does this argument make sense? Would we really save energy by following this advice?arrow_forward
- At very low temperatures the molar heat capacity of rock salt varies with temperature according to Debye's T3 law: C = k where k = 1940 J/(mol K) and 0 = 281 K. (a) How much heat is required to raise the temperature of 1.50 mol of rock salt from 13.0 K to 36.0 K? (Hint: Use the change in thermal energy in the form dQ (b) What is the average molar heat capacity in this range? (c) What is the true molar heat capacity at 36.0 K? nCdT and integrate.)arrow_forwardAlligators and other reptiles don’t use enough metabolic energy to keep their body temperatures constant. They cool off at night and must warm up in the sun in the morning. Suppose a 300 kg alligator with an early-morning bodytemperature of 25°C is absorbing radiation from the sun at a rate of 1200 W. How long will the alligator need to warm up to a more favorable 30°C? (Assume that the specific heat of the reptilian body is the same as that of the mammalian body.)arrow_forwardIt is important for the body to have mechanisms to effectively cool itself; if not, moderate exercise could easily increase body temperatures to dangerous levels. Suppose a 70 kg man runs on a treadmill for 30 min, using a metabolic power of 1000 W. Assume that all of this power goes to thermal energy in thebody. If he couldn’t perspire or otherwise cool his body, by how much would his body temperature rise during this exercise?arrow_forward
- At very low temperatures the molar heat capacity of rock salt varies with temperature according to Debye's T³ law: C = kT 03 where k = 1940 J/(mol K) and 0 = 281 K. (a) How much heat is required to raise the temperature of 1.50 mol of rock salt from 13.0 K to 36.0 K? (Hint: Use the change in thermal energy in the form dQ = nCdT and integrate.) (b) What is the average molar heat capacity in this range? (c) What is the true molar heat capacity at 36.0 K?arrow_forwardA pronghorn antelope can run at a remarkable 18 m/sm/s for up to 10 minutes, almost triple the speed that an elite human runner can maintain. For a 32 kgkg pronghorn, this requires an astonishing 3.4 kWkW of metabolic power, which leads to a significant increase in body temperature. If the pronghorn had no way to exhaust heat to the environment, by how much would its body temperature increase during this run? (In fact, it will lose some heat, so the rise won't be this dramatic, but it will be quite noticeable, requiring adaptations that keep the pronghorn's brain cooler than its body in such circumstances.) Assume the efficiency of the pronghorn to be equal to that of human.arrow_forwardWhat is the role of “loose” electrons in heat conductors? (A) Loose electrons move quickly away from hot locations, making it impossible for energy to move and making the object a good insulator. (B) Loose electrons absorb energy, giving materials a high specific heat capacity. (C) Loose electrons vibrate and emit radiation that carries energy through the material at the speed of light. (D) Loose electrons transfer energy rapidly through a solid.arrow_forward
- A small turbine runs an aircraft refrigeration system. Air enters the turbine, at 4 bar and 40°C with a velocity of 40 m/s. At the exit the air is at 1 bar, 2.5°C and having a velocity of 200 m/s. If the work output of a turbine is 52 kJ/kg of air, calculate the heat transferred per kg of air.arrow_forwardA styrofoam cooler has a total surface area of 1.3 square meters and a thickness of 2.2 centimeters. If 2.53 kilograms of ice at 0 degrees Celsius is stored inside and the outside temperature is 28 degrees Celsius, how long does it take for all of the ice to melt? Consider conduction only. The thermal conductivity of styrofoam is 0.036 W/(m*K).arrow_forwardThe average thermal conductivity of the walls (including windows) and roof of a house in the figure shown below is 4.8 x 104 kW/m - °C, and their average thickness is 20.8 cm. The house is heated with natural gas, with a heat of combustion (energy given off per cubic meter of gas burned) of 9,300 kcal/m3. How many cubic meters of gas must be burned each day to maintain an inside temperature of 27.3°C if the outside temperature is 0.0°C? Disregard surface air layers, radiation, and energy loss by heat through the ground. m3 37.0 5.00 m 8.00 m 10.0 marrow_forward
