Caption

A computer interfaced sensor measuring the temperature change of an exothermic/exergonic reaction between aluminum foil and cupric chloride. The graph shows a steady increase in the temperature of the system after the aluminum foil was added. The reaction occurs spontaneously in water. The enthalpy change indicates that it is chemically an exothermic process. The release of free energy in the form of heat indicates that the reaction is exergonic.
