Compute the volume of natural gas methane necessary to bring 3 L of water to a boil. Presume the initial temperature of the water is 33 C and the methane is at 1 bar and 25 C. Presume that methane is an ideal gas the specific heat capacity of water to be constant as well as equal to 4.184 J/g/K over this temperature range as well as the density of water to be 1.0 g/cm3. The combustion of methane is given byCH4 + 2 O2? CO2 + 2 H2O? Hcomb = -890.36 kJ/mol
