Answer:
D. Gases have the highest kinetic energy, followed by liquids, and then solids.
Explanation:
When comparing the particles of the three states of matter, that of gases are loosely packed i.e far apart from each other while those of solids are tightly packed and fixed. Particles of liquids are also closely packed together but not as rigid as in solids.
Since the particles of gases are very far apart from one another, this allows quick and random movement, hence, making them have the HIGHEST kinetic energy (energy due to motion) followed by liquids and then solids.
