Pressure is the force applied by the particles of a gas colliding with a surface such as the walls of a container.  If there is a mixture o...

Avogadro's Principle states that equal volumes of gases at equal temperature and pressure, will contain the same number of particles.  ...

In Ideal Gas Law calculations there is only one set of conditions (P,V,T), but we've added the idea of mass.

If the number of gas particles does not change, the pressure, volume and temperature will always combine to form a constant.  Because of th...

For gas laws,  standard pressure  is considered the average pressure at sea level or 1 atmosphere (atm). There are several other units us...

For gases, standard temperature is considered the freezing point of water, 0˚C.  This causes a problem with mathematical calculations.  Tem...
