Thermal Energy Calculation

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

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.
