James Joule tested the conversionof mechanical energy into internal energy by measuringtemperatures of falling water. If water at the top of a Swisswaterfall has a temperature of 10.0°C and then falls 50.0m, what maximum temperature at the bottom would Jouleexpect? He did not succeed in measuring the temperaturechange, partly because evaporation cooled the falling waterand also because his thermometer was not sufficientlysensitive.

Given, The temperature, T=10.0 oC. Distance of the waterfall, h=50.0 m.

The rate at which a resting person converts food energy is called one’s basal metabolic rate (BMR). Assume that the resulting internal energy leaves a person’s body by radiation and convection of dry air. When you jog, most of the food energy you burn above your BMR becomes internalenergy that would raise your body temperature if it were not eliminated. Assume that evaporation of perspiration is the mechanism for eliminating this energy. Suppose a person is jogging for “maximum fat burning,” converting food energy at the rate 400 kcal/h above his BMR, and putting out energy by work at the rate 60.0 W.

We know from Newton's Law of Cooling that the rate at which an object warms up is proportional to the difference between the ambient temperature of the room and the temperature of the object. The differential equation corresponding to this situation is given by y' = k(M – y) where k is a positive constant. The solution to this equation is given by y = M + (yo – M)e-kt , where yo is the initial temperature of the object. Suppose your Thanksgiving turkey is kept at a temperature of 40 degrees Fahrenheit until it is put into a 350 degree Fahrenheit oven.

The intensity of solar radiation above the earth’s atmosphere is about 1300 W/m2. The earth’s average surface temperature is relatively constant over geological time spans, so the energy the earth receives from the sun must be balanced by energy the earth reradiates in all directions into space. If the earth were to have a uniform temperature over its entire surface, what would the temperature be?
