Two objects of the same material and mass are placed in contact. One object is at 60°C, and the other is at 20°C. Describe what happens to the energy in this system.

• Energy will transfer from the cooler object to the hotter object.

• Energy will transfer from the hotter object to the cooler object until they reach the same temperature.

• Energy will transfer in both directions equally, maintaining their initial temperatures.

• No energy transfer will occur because they are of the same material.
