Select the correct answer.

If you are asked to compare matter in solid, liquid, and gaseous states, which statement best defines a gas?

A. Highest energy, highest molecular motion, and least dense packaging of molecules
B. Highest energy, highest molecular motion, and most dense packaging of molecules
C. Least energy, highest molecular motion, and least dense packaging of molecules
D. Highest energy, least molecular motion, and least dense packaging of molecules



Answer :

Final answer:

Gas particles have high energy, rapid molecular motion, and least dense packaging compared to solids and liquids.


Explanation:

The statement that best defines a gas is: highest energy, highest molecular motion, and least dense packaging of molecules. This means that gas particles have significant energy, move rapidly, and are spaced far apart compared to solids and liquids. An example of a gas is oxygen in its gaseous state (O2(g)).
