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 :

colemaikell08

Answer: A

Explanation:

Let's look at what attributes of the gas that is common with the answers:

Energy

Molecular Motion

Density of molecular packaging

Since molecular motion is just kinetic energy, we can rule out any answer there is inverse proportionality between energy and molecular motion, in this case, C and D.

Now, since they only have the different molecular densities for the attributes, we can base our answer on this attribute. We know that gasses have relatively high energy compared to the other states, which means that the molecules are moving faster than in the other states. It is allowed to move at this speed because the molecules are loose and free, meaning they are less packed, which means that A is our answer
