Question & Answer
Choose the Best Answer
In the gaseous state, water molecules move freely and rapidly, overcoming intermolecular forces, while in the solid state, they are tightly packed and vibrate in place.
Both states exhibit similar molecular motion due to the same intermolecular forces.
In the solid state, water molecules have more energy compared to the gaseous state, allowing for rapid movement.
Water molecules in both states have the same amount of kinetic energy, resulting in identical motion.
Understanding the Answer
Let's break down why this is correct
In the gas, water molecules have enough energy to break the hydrogen bonds that normally hold them together. Other options are incorrect because The idea that gas and solid have similar motion ignores the huge energy difference; It suggests solids have more energy than gases, which is not true.

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.
