Page 3: Introduction
Understanding calorimetry is the first step into the field of thermodynamics, the study of the role of heat in physical processes. With the addition of a balance, ice, and a heat source, such as PASCO’s Model TD-8556 Steam Generator, this Basic Calorimetry Set provides the equipment necessary to perform a variety of calorimetry experiments. Four... -
Page 4: Notes On Calorimetry
B a s ic C a lo r i m e t r y S e t Notes on Calorimetry A calorimeter is a vessel or device that thermally isolates an experiment from its surround- ings. Ideally, this means that the results of an experiment performed in a calorimeter are independent of the temperature of the surroundings, because no heat flows into or out of the calorimeter. -
Page 5: Experiment 1: What Is A Calorie
B a s ic C a lo r i m e t r y S e t Experiment 1: What is a Calorie? Equipment Needed • Calorimeters, 2 pieces • Thermometer • Balance • Hot and cold water Introduction When two systems or objects of different temperature come into contact, energy in the form of heat is transferred from the warmer system into the cooler. - Page 6 B a s ic C a lo r i m e t r y S e t Data Table 1.1: Data Trial 1 Trial 2 Trial 3 cal + water cold cal + water hot cold final final Calculations From your data, make the calculations necessary to determine the mass of the cold and hot water (M and M ), and also the temperature changes undergone by each...

B a s ic C a lo r i m e t r y S e t Experiment 2: Specific Heat Equipment Needed • Calorimeter • Thermometer • Samples of aluminum, copper, and lead • Balance • Boiling water • Cool water •... - Page 8 B a s ic C a lo r i m e t r y S e t Part 2: The Specific Heat of Antifreeze Repeat Part 1 of this experiment, but instead of using the metal samples, heat approxi- mately 100 g of antifreeze to approximately 60° C. Measure and record the temperature, then quickly pour the antifreeze into a calorimeter containing cool water and stir until the highest stable temperature is reached (about 1 minute).

(Can you explain why?) Immediately determine M , the mass of calorimeter plus water plus (condensed) final steam.

Page 12: Experiment 4: Latent Heat Of Fusion
B a s ic C a lo r i m e t r y S e t Experiment 4: Latent Heat of Fusion Equipment Needed • Calorimeter • Thermometer • Ice in water (at melting point) • Warm water Introduction Just as steam has a higher internal energy content than water, so water has a higher internal energy content than ice. - Page 13 B a s ic C a lo r i m e t r y S e t = ________________ final = ________________ final Calculations According to the principle of the conservation of energy, the quantity of heat absorbed by the ice as it melts and then heats up to the final equilibrium temperature must equal the quantity of heat released by the warm water as it cools down to the final equilibrium tem- perature.
