| Objectives: - Measure the mass and temperature of water in a calorimeter - Heat a metal sample of known mass to a specific temperature - Calculate the changed in water temperature caused by adding the hot metal sample: and, - Calculate the specific heat of the metal using your mass and temperature data MASS DATA TEMPERATURE DATA Material Mass Material Temperature Metal Boiling Water 100 o, Plastic Foam Cup . Water in Cup 200 Cup + Water Water Water in Cup After 31 e Added Was Metal Heat Gained By Water = 4154 3 J Q=mCAL AT=112C Questions: 1. What physical properties, other than specific heat of a metallic element if 314 joules of heat energy are needed to raise the temperature of a 50.0 g sample from 25.0 C to 50.0 C. 2. Why is water an excellent material to use in a calorimeter? 3. Calculate the 4. Propose a method for determining the specific heat, Cp, for a metal like sodium which reacts with water
