Abstract
In this experiment, two calorimeters were designed and assembled. One was made using Styrofoam cups and another one using glass and foil. The calorimeters were studied for their performance in keeping the heat of the system. They were studied by measuring the heat loss of hot water over time. The heat lost in each calorimeter over 30 minutes was calculated. The calorimeter made of glass worked better and less heat was lost in it. The assembled calorimeters were used to find out the heat of reaction between NaOH and HCl per one mole of water. This value was found ...
