A metal spoon is left in a hot cup of coffee. When the spoon is touched, the handle is very hot. How was the heat transfered from the liquid to the spoon?
conduction (metal is a conductor)

thermal energy

A mobile turns from a candle burning below it. Explain HOW the heat causes the mobile to turn. (You must state details, not just the heat transfer method.)
As the energy from the burning candles heats the air above them, the air particles move faster. The particles move farther apart as they take in the energy. This makes the air less dense. Cooler air rushes under the less dense air. It pushes the warmer air upward. As long as the candles—the heat sources—are burning, movement of the rising warm air will make the spiral twirl and the blades spin.

A pot on the stove in made of metal, but the handle is made of wood. What are the benefits of making the pot with different materials?
The metal is a good conductor. It will allow the heat to pass through it and cook the food inside of it. The wooden handle it allow the user to move pot without getting burned.

What is the difference between heat and temperature?
Heat is the transfer of thermal energy between matter with different temperature. Temperature is the measure of the average motion of particles in matter.
