Why did black block B feel colder (similar to tile/metal) to us than the block A (similar to wood/foam) in the class activity?

• Energy from your hand is transferring faster to Block B than Block A.

• The block B is a colder temperature than the Block A.

• The specific heat of Block B is higher than Block A.

• Block A is transferring energy to your hand faster than Block B.

Radiant energy becomes thermal energy when

• the radiant energy is absorbed by atoms causing them to speed up

• the radiant energy is absorbed by atoms causing a lower temperature

• the radiant energy is reflected off of atoms

• the thermal energy is absorbed by atoms

What does a diagram of atoms close together (like a piece of tile or metal) best illustrate?

• That the material is a good insulator and slows down thermal energy transfer

• That the material is a good conductor and speeds up thermal energy transfer

• That the material has a high specific heat

• That the material is a poor conductor
