How is the average speed of the molecules of an object related to the thermal energy of the object?
When the average speed of the molecules increases, the thermal energy of the object increases.
When the average speed of the molecules increases, the thermal energy of the object decreases.
The relationship between the average speed of the molecules and the thermal energy of the object depends on whether the object is a solid, a liquid, or a gas.
The average speed of the molecules is not related to the thermal energy of the object.

A student is holding a cold piece of metal in her hand. While she is holding the piece of metal, her hand gets colder. Does the piece of metal get warmer? Why or why not?
Yes, the piece of metal will get warmer because some thermal energy is transferred from the metal to the student’s hand.
Yes, the piece of metal will get warmer because some thermal energy is transferred from the student’s hand to the metal.
No, the piece of metal will stay at the same temperature because an equal amount of thermal energy is exchanged between the student’s hand and the metal.
No, the piece of metal will stay at the same temperature because thermal energy is not transferred between the student’s hand and the metal.

Which of the following describes the thermal energy of the bears?
The thermal energy of both bears will be the same because they are both in the same room.
The thermal energy of both bears will be the same because they are identical bears and started out at the same temperature.
The thermal energy of the bear in the sunlight will be greater than the thermal energy of the bear in the shade because more energy was transferred directly from the sun to the bear in the sunlight.
The thermal energy of the bear in the sunlight will be greater than the thermal energy of the bear in the shade because more energy was transferred from the ground to the bear in the sunlight.
