The air temperature above coastal areas is profoundly influenced by the large specific heat of water. One reason is that the energy released when 1 cubic meter of water cools by 1.0°C will raise the temperature of an enormously larger volume of air by 1.0°C. Estimate that volume of air. The specific heat of air is approximately 1.0 kJ/kg ? °C. Take the density of air to be 1.3 kg/m3.

2.4 g of water was evaporated from the surface of skin. How much heat, in the unit of kJ, was transferred from the body to the water to evaporate the water completely? The temperature of the skin is 33.5°C, and the latent heat of vaporization of water at 33.5°C is 43.6 kJ/mol. Molar mass of water is 18 g/mol

When it rains, water vapor in the air condenses into liquid water, and energy is released. (a) How much energy is released when 0.0318 m (1.25 inch) of rain falls over an area of 2.59×106 m² (one square mile)? (b) If the average energy needed to heat one home for a year is 1.50x1011 J, how many homes could be heated for a year with the energy determined in part (a)? (a) Number (b) Number i i Units Units >

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?
