• The transfer of energy

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?

• 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 counter top

After cooking an egg in boiling water, you cool the egg by putting it into a bowl of cold water. Which of the following explains the egg's cooling process?

• Temperature is transferred from the egg to the water

• Cold moves from the water into the egg

• Energy is transferred from the water to the egg

• Energy is transferred from the egg to the water

Amy wraps her dolls in blankets but can’t understand why they don’t warm up. Why don’t they warm up?

• The blankets she uses are probably poor insulators

• The blankets she uses are probably poor conductors

• The dolls are made of materials that don't hold heat well

• None of the above

As water in a freezer turns into ice,

• the water absorbs energy from the air in the freezer

• the water absorbs the coldness from the air in the freezer

• the freezer air absorbs heat from the water

• the water neither absorbs nor releases energy

If you put a metal spoon and a wooden spoon into a pot of boiling water, one will become too hot to touch. Why?

• Metals conduct heat better than wood

• Wood conducts heat better than metals

• Metals pull in heat because heat is attracted to metals

• Wood isn't as strong as metals

On a hot day, the upstairs rooms in a house are usually hotter than the downstairs rooms. Why?

• Cool air is less dense than hot air

• Warm air rises and cool air sinks

• The roof insulation warms the air

• Cool air rises and warm air sinks
