# Boyle’s law

Boyle’s law is an important gas law that states that at a constant temperature, the volume of gas is inversely proportional to the pressure of the gas. This means that when the temperature of a gas is kept constant, the relationship between Volume and pressure of a gas is inverse.

Another way to put the Boyle’s law is to say that with any increase in the pressure of a gas at a constant temperature, the volume of the gas decreases. Similarly with any decrease in the pressure, while maintaining a constant temperature, the volume of the gas will increase.

Further more any increase or decrease in the volume of the gas at a particular temperature will decrease and increase the pressure of the gas respectively.

The Boyle’s law which was proposed by Boyle has very important implications in modern physics. The law forms the basis of the relationship between the three important parameters of a gas i.e. Volume, Pressure and Temperature.

The knowledge of this law is also important in anesthetic practice, to understand the functioning of the Boyle’s machine which is the basic anesthesia machine and also the functioning of the oxygen and nitrous cylinders.

The two other laws apart from Boyle’s law that are essential to understand gas physics are the Charle’s law and the Graham’s law.
