Materials that allow heat to transfer through them easily or transmit heat are known as

Materials like wood and air are excellent

Materials that do NOT transfer heat well or absorb heat are known as

Materials that are good conductors also expand more when heated and contract more when cold. If I have a metal rod and a plastic rod, which one will contract more?

When particles are heated, they speed up and

When particles move slower, they

Materials that heat up quickly and cool down quickly (require less energy to heat up so have less energy to give up) have a

Materials that heat up slowly and cool down slowly (require more energy to heat up so have more energy to give up) have a

A material that has a high specific heat is
