... contained by the calorimeter. We then found the temperature at which the weight and water were equal using our mercury thermometer. We repeated this process three times using three different masses of water. After finding all of the temperatures and masses, we calculated the specific heat capacity for each ... . We also measured the weight of the mass of the cup of water, which now included the mass of the melted ice. This process was repeated three separate times for three different masses of water. The heat of fusion was calculated after these values were established. The three ... tak...
