thermal energy

A barefoot student steps on a hot concrete surface. Most of the heat transferred to the student’s skin by this contact is by the process of—

• convection
• conduction
• vaporization
• radiation

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 are insulators.

• Wood is more dense than metal.
