Water is boiling in a clear pot, as shown in the picture. how do the water molecules closest to the burner compare to the water molecules closest to the surface of the liquid? they are more spread out and moving faster than those at the surface. they are closer together and moving faster than those at the surface. they are more spread out and moving slower than those at the surface. they are closer together and moving slower than those at the surface.

The correct answer is "They are more spread out and moving faster than those at the surface".

Explanation:

The water molecules closest to the burner move faster and are more dispersed because the heat transfer to the water there is greater than at the surface. This causes the water to be more spread out and move faster due to the temperature difference. The higher the temperature, the faster the molecules move and tend to occupy a larger volume.

Have a nice day!
