Chapter 19, Problem 17EAP

One way you keep from overheating is by perspiring. BIO Evaporation—a phase change—requires heat, and the heat energy is removed from your body. Evaporation is much like boiling, 24 × 10 5 J / k g because at lower temperatures more energy is required to break the molecular bonds. Very strenuous activity can cause an adult human to produce 30 g of perspiration per minute. If all the perspiration evaporates, rather than dripping off, at what rate (in J/s) is it possible to exhaust heat by perspiring?

It’s possible to boil water by adding hot rocks to it, a technique that has been used in many societies over time. If you heat a rock in the fire, you can easily get it to a temperature of 500°C. If you use granite or other similar stones, the specific heat is about 800 J/kg ⋅ K. If 5.0 kg of water at 10°C is in a leak-proof vessel, what minimum number of 1.0 kg stones must be added to bring the water to a boil?
You are working in your kitchen preparing lunch for your family. You have decided to make egg salad sandwiches and are boiling six eggs, each of mass 55.5 g, in 0.750 L of water at 100°C. You wish to take all the eggs out of the boiling water and immediately place them in 23.0°C water to coolthem down to a comfortable temperature to hold them and peel them. You decide that you wish the mixture of the water and the eggs to reach an equilibrium temperature of 40.0°C. Explaining this to a family member, she challenges you to determine exactly how much water at 23.0°C you needto achieve your desired equilibrium temperature. Take the average specific heat of an egg over the expected temperature range to be 3.27 × 103 J/kg ? °C.
While swimming, conduction can play a big role in heat loss from the body. The body of one swimmer has a total surface area of 1.80 m2 and an average thickness of 1.60 mm. The skin's thermal conductivity is 0.370 W/m-K. If the water's temperature is 20.0°C, and the blood reaching the inner surface of the skin is at 37.0°C, what is the rate of energy loss for that person through conduction?
