Introduction: There is a fundamental relationship between pressure and volume known as Boyle's Law. This law applies to a variety of examples in the real world. One such example is the use of a syringe. With a syringe, pushing down on the plunger of the syringe leads to a decreased volume as a result of increased pressure. This relationship between pressure and volume is summarized by the equation for Boyle's Law below:

[math]P_1V_1=P_2V_2[/math], where P=pressure and V=volume

Boyle's Law is known as an inverse relationship, in that an increase in pressure will lead to a decrease in volume. This is because the product of pressure and volume are generally equal to a constant, and an increase in one variable must be compensated for by a decrease in the other variable. The graph for Boyle's Law can be demonstrated by a hyperbola.

Boyle's Law, based on the fact that it considers the pressure and the volume of a gas, operates under conditions of constant temperature. In addition to this, Boyle's Law generally works best under conditions of lower pressure, because this will lead to the gas being more ideal in its nature.
