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:             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 →

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 →

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 →

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 →
