While temperature refers to an average of the kinetic energy of particles, thermal energy refers to ———— kinetic energy

• Transferred

• Total

• Added

• Lost

Which sample has the higher temperature?

• Sample B because it has more thermal energy and more molecules

• Sample B because the molecules are brown

• Sample A because the molecules are moving faster and have more average kinetic energy

• Sample A because yellow is such a hot color

If you brought sample A and B close together , in what direction would heat be transferred?

• From sample A to sample B

• From sample B to sample A

• Heat would not be transferred.

• sample A and sample B would both transfer heat to each other.

In this picture, heat is being transferred from sample B to sample A. When will the heat transfer stop?

• Heat transfer will keep on until object B has zero thermal energy

• Heat transfer will not stop, it will keep going

• Heat transfer will stop when sample A and sample B have reached the same temperature.

even though sample A has a higher temperature, sample B has a higher thermal energy. Pick the correct explanation from the choices below

• the molecules in sample B are brown and have high energy

• the molecules in sample A are yellow and have low energy

• thermal energy is higher when temperature is lower

• there are many more molecules in sample B which make the total energy higher

As the heat moves what happens to the molecules?

• they begin to move faster

• they begin to move slower

• they stop moving

• they fly off the object
