Boyle’s Law- Pressure Volume Relationship
From his experiments Robert Boyle proposed that the volume of a fixed quantity of gas at constant pressure is inversely proportional to its pressure. P1V1 = P2V2 The process Continue Reading →

Proportionalities and the Gas Laws
Proportionalities: Mathematically, two variables are said to be proportional if there is a constant ratio between them. Directly proportional: When both variables change in the same direction Continue Reading →
Variables and Units Used in Gas Law Problems
The following abbreviations and units are commonly used: V= Volume (usually in liters) T = Temperature (always in Kelvin) P = Pressure (usually in Pascals or atmospheres) Continue Reading →
Kinetic Molecular Theory
The kinetic molecular theory allows us to explain behavior of gases through modeling. Assumptions of the kinetic molecular theory: Particles of the gas are small and have negligible volume compared Continue Reading →
States of Matter (Gases)
All matter on earth exists in one of three main states: solid, liquid, or gas. The states of matter differ in terms of particle arrangement, energy of the particles, and Continue Reading →
