Cool It Lab

Front

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?

Back

All of the above factors affect the heat energy transferred.

Front

Claim about the relationship between the type of metal and the amount of energy transferred, including all three metals.

Back

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

Front

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

Back

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

Front

What is the purpose of the investigation involving changing the mass of heated metal washers placed in room temperature water?

Back

To determine if the mass of the washers affects the amount of energy transferred.
