Air in a thundercloud expands as it rises. If its initial temperature is 300 K and no energy is lost by thermal conduction on expansion, what is its temperature when the initial volume has doubled?
solar panels have an emissivity of e=0.465. When in direct sunlight they absorb energy at rate of 857J/s per square meter of serface. Assume that only energy loss is due to the emission radiation. What equilibrium temperature are panels reaching?
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 27.0ºC.
