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
Why do we wear sweaters in cold weather?
To keep cold out
To generate heat
To reduce heat loss
All of the above
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
You have a can of soda that you want to keep cold. Which material will work best to keep it cold?
Aluminum foil
Paper Towel
Wax Paper
Wool Sock or Sweater
When you hold a metal coat hanger in a camp fire to roast a marshmallow, the coat hanger might become too hot to hold. Why might the coat hanger get too hot?
The heat radiates along the coat hanger
The heat builds up near the flame until it can’t hold it anymore and then moves
Metal atoms vibrate with more energy when they get hot, and they collide with atoms near them, which causes the neighboring atoms to vibrate.
Since metals melt in fire, they react strongly to fire and get hot easily.
An aluminum plate and a plastic plate have been in the freezer all night long. When you remove them the next morning,
The plates are the same temperature.
The plastic plate has a higher temperature.
The plastic plate has a lower temperature.
The aluminum plate has a lower temperature.
When placed in direct sunlight, which object will absorb the most radiated heat energy?
A white sweater
A snowball
Aluminum foil
A black sweater
On a warm sunny day, you will feel cooler wearing light colored clothes because they
reflect more radiated heat energy
prevent sweating
are not as heavy as dark clothes
let more air in
