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.

I am currently doing this and the answer should be A.

Explanation:

Warmer liquid rise so that means that A is hotter and B is colder this is way B is moving down. This means that C and D can not be correct, and the molecules do not grow.

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
