The easiest way to determine whether a process is exothermic or endothermic is to note the change in temperature in a calorimeter; a positive temperature change indicates an exothermic process while a negative temperature change indicates an endothermic process. Select the Experiment tab in the Simulation, and then click Run Demonstration. Perform the described tasks while specifically focusing on the third demonstration, where LiCl is dissolved in water, paying attention to the temperature change and the microscopic view. Match the...
