Suppose you want to heat air in your house with methane (CH4). Assume your house has 275 m2 of floor area and that ceiling is 2.50 m from the floor. The air in the house has a molar specific heat capacity of 29.1 j/mol*K. Average molar mass of air is 28.9 g and the density of air at these temperatures is 1.22 g/L. How much of methane do you need to burn in order to heat the air in the house from 15.0 to 22.0 oC?
