Question
In a bomb calorimeter, the reaction vessel is surrounded by water that must be added for each experiment. Since the amount of water is not constant from experiment to experiment, the mass of water must be measured in each case. The heat capacity of the calorimeter is broken down into two parts: the water and the calorimeter components. If a calorimeter contains 1.78 kg water and has a total heat capacity of 10.99 kJ/degree C, what is the heat capacity of the calorimeter components? The specific heat capacity of water is 4.18 J/g degree C. Heat capacity = kJ/degree CExplanation / Answer
total heat capacity = heat capacity of calorimeter+ heat capacity of water
10.99*1000 = heat capacity of calorimeter + mass of water* specific heat
10.99*1000= heat capacity of calorimeter +1.78*1000* 4.18
heat capacity of calorimeter = (10.99*1000 - 1.78*1000*4.18)= 3549.6 J/deg.c= 3.549 Kj/deg.c
