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? A: I think a calorimeter
measures the heat since calor means heat and meter means measure.
2. Where have you heard the word calorie before? What do you think a calorie is? A: I
have heard the term calorie be used when talking about food and the proper diet of
a human being.
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? Decreased by 55.04°c
C. How much did the temperature of the water change? Increased by 4.96°c
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 greater specific heat capacity as its temperature only changed by 4.96
degrees, whereas the temperature of the copper changed by 55.04 degrees.

, Question: What factors determine how heat energy transfers between objects?
1. Predict: In the Gizmo warm-up, you saw how 200 g of 90 °C copper transfers heat to 200 g
of 30.0 °C water.
A. How do you think increasing the water’s mass would affect the final temperature?
Increasing the waters mass will decrease the final temperature because since we are
adding more water and keeping the mass of the copper the same the final
temperature should naturally be less than what it was before.
B. How do you think decreasing the copper’s mass would affect the final temperature?
Decreasing the coppers mass will also decrease the final temperature.
C. How do you think increasing or decreasing the copper’s initial temperature would
affect the final temperature? If you increase the coppers initial temperature then the
final temperature will also increase and if you decrease coppers initial temperature
then final temperature would also decrease. They are directly proportional.
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.
