Which of the following describes the motion of the molecules in a glass of liquid water?

A. The molecules are all moving at the same speed.
B. The molecules move only when the glass of water is moving.
C. The molecules are moving farther apart.
D. The molecules are not moving.



Answer :

Final answer:

Liquid water molecules show slight mobility and random motion, leading to even dispersion in the container.


Explanation:

Liquid water molecules are slightly mobile and move around randomly, but they are still relatively close together compared to gas particles. The motion of water molecules leads to diffusion, where the molecules disperse evenly in the container. This random motion is why a mixture appears mixed even though the molecules are in constant motion.
