A pot of water is heated on the stovetop. The water molecules closest to the burner rise in the pot when they gain thermal energy. In 1-2 sentences explain why the water rises. Include the property of the water that is changing as it is heating as well as the change in kinetic energy
1 answer
The water rises because as it gains thermal energy, the water molecules near the burner increase in kinetic energy, causing them to move faster and spread out, creating a less dense area that rises to the top of the pot.
