A swimming pool 100m by 40m is filled with water to a depth, Ask an Expert

Academics

A swimming pool, 10.0m by 4.0m, is filled with water to a depth of 3.0m at a temperature of 20.2 degrees Celsius.

If the energy needed to raise the temperature of the water to 29.0 degrees Celsius is obtained from the combustion of methane (CH4), what volume of methane, measured at STP, must be burned?
