Is it the same rG and fG ? The device used to measure calorimetry is a calorimeter. Since faster moving things have more kinetic energy, adding heat increases the energy of the particle. temperature of the tap water. Add the piece of metal, and heat it up on the stove or over a Bunsen burner. Calorimetry Lab Report o PART A. The specific heat capacity of the two unknown metals were determined by measuring the transfer of heat from the metal to water, through the use of a calorimeter. Step 4: Heat the Metals to 100 C in a Hot Water Bath. 2. The change in heat can tell us if the reaction is either exothermic - it released or heat into surroundings, or endothermic - it absorbed heat from surroundings. Abstract: In this experiment, the specific heat and the density of an unknown metal was determined in order to identify the unknown metal. Specific heat values are also commonly given in cal/gC, where 1 calorie=4.184 Joules. The overall field of thermodynamics involves the study of thermal processes in physical systems.
