When it rains, water vapor in the air condenses into liquid water, and energy is released. (a) How much energy is released when 0.0285 m (1.12 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 1.50×1011 J, how many homes could be heated for a year with the energy determined in part (a)?
