During summer camp, Kate learns the names of the stars that make up the Summer Triangle: Deneb, Altair, and Vega. Over the campfire, Kate discusses how the energy from the surfaces of these hot stars traveled light-years through the vacuum of space to make it to her and her fellow campers’ eyes. Based on this discussion, Kate knows that this starlight is an example of what form of thermal energy transfer?

• radiation

• conduction

• convection

• induction

Isabelle holds an ice cube in her hand. After a few minutes, the ice cube is completely melted. How did energy transfer from her hand to the ice cube?

• radiation

• conduction

• convection

• induction

Suppose you walk into a cold room. There are several metal chairs and wooden chairs that have been in the room for a long time. Why does a metal chair feel colder than a wooden chair?

• The metal chair conducts heat from your body better than the wooden chair.

• The metal chair conducts cold into your body better than the wooden chair.

• The wooden chair radiates heat from the chair to your body.

• The metal chair radiates heat from your body to the chair.
