• Heat travels easily through plants but not metals.

• Heat travels easily through metal objects but not through plants.

• Heat travels easily through both plants and metals.

• all of them

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.

• a hot liquid or air that expands, becomes less dense, and rises or becomes more dense, and sinks.

• When heat transfers from objects that are touching.

• When heat transfers through the heater or AC in your house.

The higher the average kinetic energy the __________________

• the higher the volume

• the higher the mass

• the higher the temperature

• the higher the density
