Mass of water in a calorimeter = 90.0 g
Initial temperature of water in calorimeter = 22.0 oC
Mass of unknown metal = 45.0 g
Initial temperature of hot metal = 100.0 oC
Final temperature of water after you place hot metal in calorimeter filled with water = 28.0 oC
Based on the above data, what is the Cp of the metal?
(Cp H2O = 4.184 J/g oC )Answer Question

under constant volume conditions, the heat of combustion of benzoic acid, is 26.38 kj/g. A 1.200 g sample of benzoic acid is burned in a bomb calorimeter. The temperature of the calorimeter increases from 22.45 degrees Celsius to 26.10 degrees Celsius.

What is the...

(a) total heat capacity of the calorimeter
(b) if the calorimeter contained 1.5 kg water, what is the heat capacity of the calorimeter when it contains no water?
(c) What temp increase would be expected in this calorimeter if the 1.200 g sample of benzoic acid were combusted when the calorimeter contained 1.00 kg water?
