The Properties of Gases

This topic is a discussion on the perfect gas equation, starting from introducing pressure and temperature characters based on gas molecular aspect. It is also a revision on well known laws: Boyle, Charles and Avogadro. These principles lead us towards the kinetics model of gases. From both kinetic model and perfect gas equations, we able to derive an equation to estimate the velocity of a gas. The equation even more refined by applying Maxwell distribution where the two factors; mass of gas molecules and temperature of a gas were considered. These factors are similarly important as the frequency of gas molecules hitting each other and the wall. From these factors, we are also able to derive equation of the root means square speed, relative speed, mean speed and most probably speed.
