Overview

Matter exists in three states: solid, liquid, and gas. Among these, gases show unique behavior due to large intermolecular distances and negligible intermolecular forces. In this chapter, we explore the physical properties of gases and the laws that govern their behavior under varying conditions of

Key Concepts

Boyle’s law states that at constant

Boyle’s law states that at constant temperature, volume is inversely proportional to pressure (V ∝ 1/p). Charles’ law states that at constant pressure

Combining Boyle’s

Combining Boyle’s, Charles’, and Avogadro’s laws gives the equation pV = nRT, where R is the universal gas constant (0.0821 L atm mol⁻¹ K⁻¹). This equ

The total pressure of a non

The total pressure of a non-reacting gas mixture is the sum of the partial pressures of each gas. Partial pressure of a gas = mole fraction × total pr

At constant temperature and pressure

At constant temperature and pressure, the rate of diffusion or effusion of a gas is inversely proportional to the square root of its density or molar

Gases consist of tiny particles

Gases consist of tiny particles in constant random motion. There are no intermolecular forces, collisions are perfectly elastic, and pressure results
