Specific heat values are also commonly given in cal/gC, where 1 calorie=4.184 Joules. /Filter /FlateDecode Then measure the mass of the water and reassemble, the calorimeter. We setup the calorimeter and got a mass of it just being empty then we got a mass with 30mls of water in it. Navannah Jones 05/13/21 Chemistry Calorimetry and specific heat Purpose-The purpose of this lab was to find the specific heat of something that can be set on using a calorimeter. The purpose of this lab experiment is to measure the specific heat capacity of unknown metal samples and also to determine the latent heat of fusion of water.
