Answer:
The reason gases lack a fixed volume is key.
Explanation:
There are three states of matter: solids, liquids, and gases. Solids maintain a constant shape and volume, whereas liquids have a set volume but no specific shape. Gases do not retain either a fixed shape or volume. While solid particles are tightly packed, the particles in a gas are spaced further apart, with minimal force of attraction between them.
Upon opening the perfume bottle, some of the liquid transitions into gas, and its scent disperses throughout the room because gas particles are loosely arranged and the forces holding them together are weak. They expand freely without a fixed volume.
