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?
- An calorimeter measures quantities of absorbed or emitted heat or for determining
specific heats.
2. Where have you heard the word calorie before? What do you think a calorie is?
- A calorie is a unit of thermal 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_____
B. How much did the temperature of the copper change? ______-4.96__________
C. How much did the temperature of the water change? ____________________
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.
2. Collect data: Use the Gizmo to determine the final temperature for each set-up listed below.
Record your results in the tables. In the first table, you experiment with changing the water’s
mass. In the second table, you change the copper’s mass. In the third table, you change the
initial temperature of the copper. The first row of each table has been completed for you.
Copper Water Final Temp.

100 °C 200 g 30.0 °C 200 g
50 °C 200 g 30.0 °C 200 g
