But when necessary, such volume is converted to a volume of oil of equivalent enthalpy of combustion.

I was wondering how they measured these things, is this the enthalpy of formation, or the enthalpy of combustion of the constituent products or something?

In a recent experiment at school I calculated the molar enthalpies of combustion of four common alkanols : methanol, ethanol, 1-propanol and 1-butanol.

Assuming an enthalpy of combustion for O 2 of 20.1 joules per milliliter, we would then calculate the heat production ( and therefore metabolism ) for the mouse as 703.5 J / h.

For teaching experiments designed to measure the difference in energy between the cis-and trans-isomers, a measured quantity of carbon can be ground with the subject compound and the enthalpy of combustion computed by difference.

I was just wondering where I can find information listing molar enthalpies of combustion of common alkanols and what the reason is for differences between each alkanol in terms of heat of combustion ? thanks Wbchilds 03 : 32, 19 January 2007 ( UTC)

This famous practical is supposed to show that there is a regular rise in molar enthalpies of combustion, which is ascribed to each one having an extra-CH 2-group .-- G N Frykman 07 : 20, 19 January 2007 ( UTC)

Methane has a higher boiling point of 111 K, a liquid density of 422.62 g / l = 26.3 mol / l, and a standard enthalpy of combustion of-891 kJ / mol, thus it has an energy density of 23, 472 kJ / mol 23, 472 kJ / l, and is clearly the best choice of the 3 gases if volume is the limiting factor and refrigeration is possible . talk ) 18 : 37, 17 December 2007 ( UTC)
