• It is larger than Cube B.

• It is cooler than Cube B.

• It is smaller than Cube B.

• It is warmer than Cube B.

Multiple Choice

How does heat transfer when you hold an ice cube in your hand?

• Shrink

Multiple Choice

The faster molecules move, 

• the higher the temperature
• the less temperature
• the same temperature
• I don't know

Multiple Choice

• it gains heat from the hot water and expands.
• loses heat from the hot water and contracts. 
• the surrounding air is too warm. 
• the liquid is boiling. 

Multiple Choice

• the freezer air absorbs heat from the water.

• the water neither absorbs nor releases energy

Multiple Choice

You take a cold can of soda off of a counter top. The counter top underneath the can feels colder than the rest of the counter. Which of the following explains this occurrence?

• The cold has been transferred from the soda to the counter.

• There is no heat energy left in the counter beneath the can.

• Some heat has been transferred from the counter to the soda.

• The heat beneath the can moves away into other parts of the countertop.

Multiple Choice
