Question & Answer
Choose the Best Answer
High temperature and high pressure
Low temperature and low pressure
Constant pressure at room temperature
Variable temperature at atmospheric pressure
Understanding the Answer
Let's break down why this is correct
When a liquid is heated and pressurized enough, its molecules gain enough energy to move freely but stay close together. Other options are incorrect because Low temperature and low pressure keep molecules too far apart to merge phases; Constant pressure at room temperature cannot provide enough energy for molecules to behave like gas.

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.
