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
