Boyles Law for Behavior of Gas

Boyle's law (sometimes referred to as the Boyle–Mariotte law , or Mariotte's law is an experimental gas law which describes how the pressure of a gas tends to decrease as the volume of a gas increases. A modern statement of Boyle's law is:

P₁V₁ = P₂V₂

The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system .

P₁ and V₁ are initial pressure and volume; P₂ and V₂ are final conditions.  

The equation shows that, as volume increases, the pressure of the gas decreases in proportion. Similarly, as volume decreases, the pressure of the gas increases.
