A group of students conducted an experiment using a coffee cup calorimeter Initially the calorimeter contained only deionized water and the temperature of the water was 21 24 C After adding a soluble ionic compound and stirring the temperature reached 23 56 C The temperature of the mixture rose because the water absorbed thermal energy from the ionic compound the solution absorbed heat from the surroundings the dissolution process was endothermic the dissolution process was exothermic
