Behaviour of Gases and States of Matter

Vocabulary flashcards covering the characteristics of solids, liquids, and gases, molecular arrangements, and the definition and formula of gas pressure based on the lecture.

Intermolecular Force in Solids

The very strong attractive force between molecules that prevents them from moving from one place to another, giving solids a definite shape and a definite volume.

Intermolecular Space

The space between the molecules of a substance, which is very small in solids, larger in liquids, and very large in gases.

Liquid State

A state of matter characterized by weaker intermolecular forces and larger spaces than solids, having a definite volume but no definite shape, taking the shape of the vessel it is kept in.

Gaseous State

A state of matter where intermolecular forces are extremely weak and intermolecular spaces are very large, resulting in neither a definite shape nor a definite volume.

Pressure Exerted by a Gas

The force exerted per unit area on the walls of a container caused by the continuous collisions of gas molecules moving freely in all directions.

Formula for Pressure

The mathematical relationship defined as $\text{Pressure} = \frac{\text{Force}}{\text{Area}}$.
