Meaning

Boyle's Law states that for a fixed mass of gas at constant temperature, the product of its pressure and volume is constant.

About Boyle's Law

Boyle's Law is expressed mathematically as 𝑃×𝑉=constant
Boyle's Law describes the inverse relationship between the pressure and volume of a gas.
Boyle's Law assumes ideal gas behaviour.
Boyle's Law applies to ideal gases under constant temperature conditions.
Boyle's Law is applicable in various real-world scenarios such as breathing and syringes.
Boyle's Law is used to predict the behaviour of gases which are modelled as ideal gases.
Boyle's Law is fundamental to understanding gas laws and kinetic theory.
Boyle's Law helps in applications such as breathing mechanics and pneumatic systems.

Formula

\(p\times𝑉=constant\)

Where:

p is pressure

and

𝑉 is volume

When there is a change of pressure and volume of a known amount of an ideal gas at constant temperature the following formula can be used:

\(p_1\times𝑉_1=p_2\times𝑉_2\)

Where the number represents before and after the change.

Examples

Compressing a gas in a piston decreases its volume and increases its pressure.
In scuba diving, the pressure of air in tanks decreases as the diver uses the air and the volume increases.
