The energy value for the 1 .2 g sample of chocolate-chipin kJ/g should be calculated if it is burned in a calorimeter and increase the temperature of 360 g of water from 23 ° C to 40 ° C . Concept Introduction : A simple calorimeter is the device that is used to measure the amount of heat involved in a chemical or physical process. During any exothermic chemical process, the heat is released so temperature increases whereas during an endothermic chemical process temperature decreases as the heat is absorbed. The heat change and specific heat can be related with the given formula: q = m × C × Δ T
