When you hold an ice cube in your hand, heat is transferred from...
The ice cube to your hand.
Your hand to the ice cube.
It just appears in the ice cube.
Nowhere, because it isn't transferred.

in a freezer
near a hot fire
outside in a snowstorm
at sea-level
What happens to particles as the temperature goes up?
nothing
they don't move
they slow down
they speed up
Heat transfer always goes from ___.
hot to cold
cold to hot

What is the difference between heat and temperature?
Temperature measures the motion of molecules, and heat is the energy of that motion.
Temperature is measured by a thermometer, and heat is measured by a barometer.
Heat is measured in calories, and temperature is measured in joules.
Heat is caused by the sun, and temperature is caused by conditions in the atmosphere.
Why is there more heat in an iceberg than in a pot of boiling water?
The pot insulates the heated molecules.
Most icebergs are fairly warm to the touch.
Icebergs contain many more molecules than pots of water.
Water does not hold heat very well.
What happens inside a thermometer when the temperature goes up?
The heat causes the liquid to become denser.
The heat causes the liquid to expand.
The heat causes the liquid to float.
The heat boils the liquid into a gas.
