Vocabulary: calorie, calorimeter, joule, specific heat capacity

Prior Knowledge Questions (Do these BEFORE using the Gizmo.)

1. The Latin word calor means “heat,” and meter comes from the Greek word meaning “to

measure.” What do you think a calorimeter does? The calorimeter is an instrument used to

measure heat or heat energy and any changes in it.

2. Where have you heard the word calorie before? What do you think a calorie is? When I

hear calorie I think it’s about losing weight with your foods. I think a calorie is an ingredient,

or type of energy. I also know that people sometimes tend to worry about how much

calories they intake, and whatnot. And I also know that you can burn calories, which can

suggest that it is a type of energy.

Gizmo Warm-up

A calorimeter is an insulated container filled with a liquid,

usually water. When a hot object is placed in the calorimeter,

heat energy is transferred from the object to the water and the

water heats up.

Calorimeters can be used to find a substance’s specific heat

capacity. You will use the Calorimetry Lab Gizmo to

determine the specific heat capacities of various substances.

1. On the SIMULATION pane, select Copper. Use the slider to set its Mass to 200 g. Set the

Water mass to 200 g. Check that the Water temp is set to 30.0 °C and the copper’s Temp

is 90 °C. Select the GRAPH tab, and click Play ( ).

A. What was the Final temperature of the copper and the water? 34.96*C

B. How much did the temperature of the copper change? 55.04

C. How much did the temperature of the water change? 4.96

2. Specific heat capacity can be described as a substance’s resistance to temperature

changes. Which substance has a greater specific heat capacity, copper or water? Explain.

Water has a high specific heat capacity because it has a limit on its ability to change in

temperature with that said more energy is now needed to increase the temperature of water

compared to copper. The metals in copper are tightly bunched/packed together and that is

why the heat is transferred easily. Which means the quantity of energy needed to heat up

copper is smaller compared to water
