The diagram below shows three different types of heat transfer. Correctly label Part b.

• conduction

• convection

• radiation

Refer to the diagrams below. If red arrows represent "warm" energy and blue arrows represent "cool" energy, which diagram BEST explains the heat transfer between the koala and the tree on a hot day? Why? (Note: the koala is warmer than the tree).

• because on a hot day the tree trunk is warmer than the koala's body and koalas want to warm up.

• because on a hot day the tree trunk is cooler than the koala and heat leaves the koala's body and is transferred to the cool tree cooling the koala down.

• because on a hot day the tree trunk is cooler than the koala and the coolness is transferred to the koala's body.

• because on a hot day the tree trunk is cooler than the koala and as heat transfers from the koala to the tree, the coolness from the tree transfers to the koala.

What do collisions between particles transfer?

• Coolness

• Kinetic Energy

• Potential Energy

• Size
