Gases: Introduction

Explore pressure, volume, temperature, and the Ideal Gas Law

The Ideal Gas Law PV = nRT relates pressure, volume, amount (moles), and temperature of an ideal gas. Boyle's Law (constant T): pressure and volume are inversely proportional. Charles's Law (constant P): volume and temperature are directly proportional. Real gases deviate from ideal behavior at high pressures and low temperatures when intermolecular forces become significant.
