At the beginning of the summer, the 70.0 m3 of water in a back-yard swimming pool must be heated from 4.87 oC to 26.4 oC. The heat is supplied from a natural gas fired heater and the efficiency of transferring the heat from the combustion reaction to the water is 65%.
The mass (in kg) of methane that must be burned to cause this temperature change in the water? (The enthalpy of combustion of methane is -803 kJ mol-1.) is 193.4 kg.
The heater generates 30.0 kW of power. 89.87 hours of heat is required.
What volume of CO2(g) (in L), measured at 21oC and 1.01 bar will the heater generate in this time?
