MEASURING ENERGY CHANGESCalorimeter—a device used to measure energy given off or absorbed during chemical changes. Reinforce the LAW OF CONSERVATION OF ENERGYEXAMPLE AND DRAWING OF AN EXO REACTIONWill temperature of the water go up or down?EXAMPLE AND DRAWING OF AN ENDO REACTIONWill temperature of the water go up or down?SPECIFIC HEATSPECIFIC HEAT (Cp)—the heat required to raise the temperature of one gram of substance by one Celcius degree. Every substance has its own specific heat.

How much heat is lost when a solid aluminum ingot with a mass of 4000 g cools from 500ºC to 100ºC?CAl = .903 J / g * Cºq = (4000 g) * (500-100ºC) * (.903 J / g * Cº)
