the diagram shows the motion of a group of water molecules over a heat source. how do the molecules at point a compare to the molecules at point b? they are farther apart. they have increased in size. they have lost energy. they are moving slower.

the diagram shows the motion of a group of water molecules over a heat source. how do the molecules at point a compare to the molecules at point b? they are farther apart. they have increased in size. they have lost energy. they are moving slower.

Answer

Explanation:

Step1: Understand heat - induced molecular behavior

When water is heated, molecules gain energy.

Step2: Analyze point A

Point A is closer to the heat source. Molecules at point A gain more heat energy.

Step3: Compare with point B

Molecules at point A have more energy than those at point B. With more energy, they move faster and spread out more.

Answer:

They are farther apart.
