Focus Question: How do the type of matter, the mass of matter, and the temperature change of matter affect the amount of heat energy transferred by a sample of matter within a closed system?

• The type of matter does not affect the heat energy transferred.

• The mass of matter affects the heat energy transferred.

• The temperature change of matter does not affect the heat energy transferred.

• All of the above factors affect the heat energy transferred.

Make a claim, using quantitative data as evidence, about the relationship between the type of metal and the amount of energy transferred. (Remember that, in this investigation, the change in temperature of the water is directly related to the amount of energy transferred). All three metals must be included in your claim.

• The type of metal does not affect the amount of energy transferred.

• Different metals transfer different amounts of energy, as evidenced by varying temperature changes in water.

• All metals transfer the same amount of energy, resulting in identical temperature changes in water.

• The amount of energy transferred is inversely proportional to the type of metal used.

What is the relationship between a metal, heated to different initial temperatures, and the amount of energy transferred?

• The higher the initial temperature, the more energy is transferred.

• The lower the initial temperature, the more energy is transferred.

• The initial temperature does not affect the amount of energy transferred.

• Energy transfer is inversely proportional to the initial temperature.

What is the effect of heating copper to different initial temperatures on the amount of energy transferred?

• The amount of energy transferred increases with higher initial temperatures.

• The amount of energy transferred decreases with higher initial temperatures.

• The amount of energy transferred remains constant regardless of initial temperatures.

• The amount of energy transferred is not affected by initial temperatures.
