1) Which direction does thermal energy transfer? *

Cold to hot

Hot to cold

Either direction

Neither, they just mix

2) How does thermal energy transfer? *

Faster particles move past other particles.

Slower particles bump into faster particles, slowing them down.

Particles vibrating at a higher speed bump into those next to them.

The colder particles move.

3) A metal spoon has denser particles than a wooden spoon. If both were placed in a hot pot of water, which would be a better conductor? *

the metal spoon

the wooden spoon

Both spoons would be equal conductors

It depends on the heat of the water.

4) The Willy Warm Gloves were an example of a good *

insulator

conductor

5) Why is air a good insulator in between windowpanes? *

Air on its own is warmer than all solids

Air is a gas, so the particles are farther apart and cannot conduct thermal energy as easily.

Air is a gas, so its higher density of molecules allows it to conduct thermal energy more easily.

Air on its own cooler than all solids.
