Description

(Physical Chemistry) the Caloric value of food (in fact, the enthalpy of combustion per unit mass of food) can be determined by measurement of the heat released during the combustion of a weighted sample of food under condition of constant volume in the bomb calorimeter. The heat released by complete combustion of 1 g (3*10-3 mole) of chicken fat in these conditions (constant volume) is 10 kcal at 37° C Determine the calorific value of chicken fat (cal*g-1) at 37° C and constant pressure, i.e., the standard heat of combustion chicken fat at 37° C. the Reaction can be represented by the equation С20Н32О2 (TV) + 27О2 ()- >20СО2 (g) + 16Н2О (W).
