QuestionWhen it rains, water vapor in the air condenses into liquid water, and energy is released. (a) How much energy is released when 0.0479 m ( 1.89 inch) of rain falls over an area of $2.59 \times 10^{6} \mathrm{~m}^{2}$ (one square mile)? (b) If the average energy needed to heat one home for a year is $1.50 \times 10^{11} \mathrm{~J}$, how many homes could be heated for a year with the energy

Studdy Solution
Calculate the number of homes that can be heated using the formula:
$$\text{Number of homes} = \frac{\text{Total energy}}{\text{Energy per home}}$$
$$\text{Number of homes} = \frac{2.8070336 \times 10^{14} \, \text{J}}{1.50 \times 10^{11} \, \text{J/home}} \approx 1871 \, \text{homes}$$
The energy released can heat approximately $1871$ homes for a year.
