Compressed air can be pumped underground into huge caverns as a form of energy storage. The volume of a cavern is 6.3 x 105 m³,5and the pressure of the air in it is 7.4 × 106 Pa. Assume that air is a diatomic ideal gas whose internal energy U is given by U = nRT.If one home uses 30.0 kWh of energy per day, how many homes could this internal energy serve for one day?

From ideal gas law,Thus, we can find the internal energy to be,
