WebbFrom the table we see that 1 mole of methane gas, CH 4(g), undergoes complete combustion in excess oxygen gas releasing 890 kJ of heat. The molar heat of combustion of methane gas is tabulated as a positive … WebbAt ambient pressure and temperature the isobaric specific heat, C P, of liquid methanol is 2.53 [kJ/kg K] or 0.605 [Btu/lb °F] = [cal/g K], while the isochoric specific heat, C V, is 2.12 [kJ/kg K] or 0.506 [Btu/lb °F] = [cal/g K]. However, the specific heat - C P and C V - will vary with temperature.
WebbMethanol is a liquid from −97.6 to 64.7 °C (−143.7 to 148.5 °F) at atmospheric pressure. The volumetric energy density of methanol is an order of magnitude greater than even highly compressed hydrogen, about two times greater than liquid hydrogen and 2.6 times higher than lithium-ion batteries.
