Gases

Overview


Pressure


Pressure is a unique property of gases and liquids, but it exists in its purest form in a gas. A gas will expand to fill the volume that it finds itself in. After this has ocurred, it then exerts a force on the walls of the volume it is contained within. This force is called pressure.

Pressure is measured as
{% Pressure = force / area %}
In the SI system, force is measured in Newtons ({% N %}) and area is measured in meters squared {% m^2 %}.

Ideal Gas Laws


The Ideal Gas Law encapsulates the basic relationships among the pressure, volume and temperature of a gas. It represents a culmination of the following relationships.

  • Boyles Law
  • Charles Law

Mixture Gas Laws


  • Daltons Law of partial pressures
