Specific Heat Experiment w Directions: – Place 50 ml of cool tap water into the calorimeter. Record temperature. – Record temperature of sample from hot plate. – Insert sample into calorimeter. – After equilibrium, record final temperature of water. Supplies: 1. Calorimeter (Cup and Lid) 2. Thermometer 3. 50 ml of cool tap water 4. 2 Samples of Heated Metal

Heat Calculation for Water w Use the “heat calculator” spreadsheet to calculate the heat added to the water w User Inputs: – Mass of sample – Specific Heat of substance (a list of substances is provided with the spreadsheet) – Temperature values w Program Outputs: – Heat added to water

Calculation of Specific Heat of Sample w Using the “heat calculator, ” find the specific heat of your sample. w Go to the SED 555 newsgroup to input your data for class averaging. w Input this specific heat into the newsgroup heading—Class Results-Specific Heat
