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)

Food is similar to hydrocarbon and carbohydrate fuels, and when it is oxidized to carbon dioxide and water, the energy released is analogous to the heat of combustion ( though not assessed in the same way as a hydrocarbon fuel see food energy ).
43.
This affects first the gross energy that is assigned to carbohydrate sucrose has a heat of combustion of 3.95 kcal / g ( 16.53 kJ / g ) and starch 4.15 kcal / g ( 17.36 kJ / g ).
44.
Empirical constants such as bond dissociation energy, standard heat of formation ( ?H f ?), and heat of combustion ( ?H c ?) are used to predict the stability of molecules and the change in enthalpy ( ?H ) through the course of the reactions.
45.
This is the same as the thermodynamic heat of combustion since the enthalpy change for the reaction assumes a common temperature of the compounds before and after combustion, in which case the water produced by combustion is condensed to a liquid, hence yielding its latent heat of vaporization.

The difference between coal and coke in CO 2 production per unit energy produced depends upon the moisture in the coal ( increases the CO 2 per unit energy heat of combustion ) and volatile hydrocarbon in coal and coke ( decrease the CO 2 per unit energy ).

Here's some gritty details on empirically derived heat of combustion for diamond [ http : / / nvlpubs . nist . gov / nistpubs / jres / 21 / jresv21n4p475 _ A1b . pdf, in case anyone is interested . talk ) 18 : 41, 15 April 2016 ( UTC)

It has a lower rate of flame spread, a lower rate of heat release, a lower heat of combustion, and does not melt or drip; it forms a char which is insulating and self-extinguishing, and it contributes less to toxic gases and smoke than other flooring products when used in carpets.

But this leaves out earlier stages in the chain : presumably not all of the potential heat of combustion of food is realised in respiration; and also I think about 10 % of the energy from food has to be ` ploughed back', so to speak, into the work of digesting food, so there's another 10 % energy loss.

Once it's known the Cv of the bomb, the heat of combustion of the flammable compound ( C FC ), of the wire ( C W ) and the masses ( m FC and m W ), and the temperature change ( ?T ), the heat of combustion of the less flammable compound ( C LFC ) can be calculated with:
