Question & Answer
Choose the Best Answer
Gases have a lower molecular mass than liquids
Molecules in gases are far apart compared to those in liquids
Liquids have more energy than gases
Gases contain fewer molecules than liquids
Understanding the Answer
Let's break down why this is correct
Gases have molecules that are far apart. Other options are incorrect because People sometimes think lighter molecules mean a gas is easier to compress; The belief that liquids have more energy than gases is incorrect.

Definition
States of Matter refer to the physical forms substances can exist in, such as solid, liquid, and gas. Liquids are incompressible due to closely packed molecules, while gases are compressible since their molecules are far apart. Understanding the differences in molecular arrangement helps explain properties like compressibility and density.
