Boyle's Law: The Gas Laws Part Two---Science Blog Post

Robert Boyle of Ireland is another scientist involved in the gas laws.  He was born is Ireland on January 25, 1727 and died in England on December 31, 1691.  Boyle was a philosopher, chemist, inventor, writer, and physicist.  Like Jacques Charles, Robert Boyle also greatly influenced the world of chemistry.
He proved the relationship between the volume and pressure of a gas in a law which we now call Boyle's Law.  Boyle's Law states the a gas's volume is inversely proportional the the pressure of the gas if both the number of particles and the temperature are constant.    
This relationship is described by the equation:

  

In this equation, P1  represents the pressure of the gas before the change occurred, and V1  represents the volume of the gas before the change occurred.  The gas’s pressure after the change happened is represented by P2, and the volume of the gas after the change happened is represented by V2.    

Unlike Charles's Law, Boyle's Law is an inverse relationship.  This means that as the volume increases, the pressure will decrease.  Or vice versa, if the volume decreases the pressure will increase.
