In cold weather, you can sometimes "see" your breath. What you are seeing is a mist of small water droplets, the same as in clouds and fog. Suppose air leaves your mouth with temperature 35°C and humidity 0.035 kg/m3 and mixes with an equal amount of air at 5°C. and humidity 0.005 kg/m3 What is the relative humidity of the mixed air if its temperature and humidity equal the averages of those of the two original air masses? Represent what happens by plotting three points in a graph like Figure 5.34.
Following Vigorous exercise, the body temperature of an 80.0kg person is 40.0C. At what rate in watts must the person transfer thermal energy to reduce the body temperature to 37.0C in 30.0 min, assuming the body continues to produce energy at the rate of 150 W? (1watt=1joule/second or 1W=1J/s ).
Death Valley holds the record for the highest recorded temperature in the United States. On July 10, 1913, at a place called Furnace Creek Ranch, the temperature rose to 134F. The lowest U.S. temperature ever recorded occurred at Prospect Creek Camp in Alaska on January 23, 1971, when the temperature plummeted to 79.8F. (a) Convert these temperatures to the Celsius scale, (b) Convert the Celsius temperatures to Kelvin.
Calculate the temperature the entire sky would have to be in order to transfer energy by radiation at 1000W/m2 —about the rate at which the Sun radiates when it is directly overhead on a clear day. This value is the effective temperature of the sky, a kind of average that takes account of the fact that the Sun occupies only a small part of the sky but is much hotter than the rest. Assume that the body receiving the energy has a temperature of 27.0C.
For the human body, what is the rate of heat transfer by conduction through the body’s tissue with the following conditions: the tissue thickness is 3.00 cm, the change in temperature is 2.00C, and the skin area is 1.50m2. How does this compare with the average heat transfer rate to the body resulting from an energy intake of about 2400 kcal per day? (No exercise is included.)
