What is the total heat capacity of the calorimeter? Under constant-volume conditions the heat of combustion of benzoic acid (C6H5COOH) is 26.38kJ/g. A 2.760 - g sample of benzoic acid is burned in a bomb calorimeter. The temperature of the calorimeter increases from 21.10C to 29.97 C. Under constant-volume conditions the heat of combustion of benzoic acid (C6H5COOH) is 26.38kJ/g. A 2.760 - g sample of benzoic acid is burned in a bomb calorimeter. The temperature of the calorimeter increases from 21.10C to 29.97 C. A 1.430 - g sample of a new organic substance is combusted in the same calorimeter. The temperature of the calorimeter increases from 22.14C to 27.09C. What is the heat of combustion per gram of the new substance? Under constant-volume conditions the heat of combustion of benzoic acid (C6H5COOH) is 26.38kJ/g. A2.760 - g sample of benzoic acid is Part C burned in a bomb calorimeter. The temperature of the calorimeter increases from 21.10C to 29.97 o. Suppose that in changing samples, a portion of the water in the calorimeter were lost. In what way, if any, would this change the heat capacity of the calorimeter? the heat capacity decreases the heat capacity increases the heat capacity stays the same
