What do you think is more important for understanding the energy content of foods, enthalpy or internal energy?

Solutions

Expert Solution

Enthalpy is nothing but the total heat content ofa syste.(here:food)

internal energy :

Internal Energy (E) measures the energy state of a system as it undergoes chemical and/or physical processes.

The relationship between the internal energy of a system and its heat and work exchange with the surroundings is:

E = q + w

and relation between enthalpy and internal energy is

H= E + pEV

we can actually calculate caklorific energy value of food from H

so from formula H = m C T the energy released from food can be measured.

so H is more related to energy of food

Enthalpy H is a measure of the energy content of a system at constant pressure. Chemical reactions involve changes in enthalpy, ΔH, which can be measured and calculated: ΔHrxn∘=∑productsmΔHf∘−∑reactantsnΔHf∘ where the subscript "rxn" is for "enthalpy of reaction" and "f" is for "enthalpy of formation" and m and n represent the appropriate stoichiometric coefficients for each substance. The following table lists some enthalpy of formation values for selected substances. Substance ΔHf∘ (kJ/mol) NaOH(aq) −469.1 MgCl2(s) −641.8 NaCl(aq) −407.3 Mg(OH)2(s) −924.5...
