Question

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 1

The answer would be A( highest energy, highest molecular motion, and least dense packaging of molecules)

Why?- Because it's not sensible to heat Carbon Dioxide.

Answer 2

The answer is A. Gases are spread throughout the air and not packed tightly together. therefore the molecules move quickly and are least densely packaged. They have the highest energy because they also have the highest molecular motion.
