H Gizmos Worksheet CalorimetryLab

This calorimetry lab explores how heat transfers between substances. Students measure temperature changes of copper and water to determine specific heat capacity, showing that water resists temperature change more—indicating a higher specific heat.

GizmosName:Date:Student ExpicraticnCalorimetry LabDirections: Follow the instructions to go through the simulation. Respond to the questions andprompts in the orange boxes.Vocabulary: calorie, calorimeter, joule, specific heal capacityPrior Knowledge Questions (Do these BEFORE using lhe Gizmo.)1.The Lalin wordcaiormeans "heal,' and meter comes from the Greek word meaning "to measure." What doyou think a calorimeter does?Measure heal2.Where have you heard lhe word calorie before? What do you think a calorie is?I heard it when talking about food and daily calorie intake. Calories are something thatprovides energy and is unhealthy if taken too much.Gizmo Warm-upA calorimeter is an insulated container filled with a liquid, usually water.When a hot object is placed in the calorimeter, heat energy is transferredfrom lhe object to lhe water and the water heats up.Calorimeters can be used to find a substance s specific heat capacity. Youwill use lheCalorimetry LabGizmo to determine lhe specific heal capacitiesof various substances.1.On the SIMULATION pane, select Copper. Use the slider Io set its Mass to 200 g. Sei lhe Water mass to200 g. Check that the Water temp is set to 30.0=C and the copper's Temp is 90:C.Select the GRAPHtab. and click Play {}. This is "Trial 1"A.What was the Final temperature of the copper and lhe waler?34.96:CB.How much did the temperature of the copper change?decreased 55.04°CC.How much did the temperature of the water change?Increased 4.96 '"C2.Specific heat capacity can be described as a substance's resistance Io temperature changes. Whichsubstance has a greater specific heat capacity, copper or water? Explain.
