Key Stage 5

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

  • Expressed mathematically as 𝑃×𝑉=constant
  • Describes the inverse relationship between the pressure and volume of a gas.
  • Assumes ideal gas behaviour.
  • Applicable in various real-world scenarios such as breathing and syringes.

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 a substance 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.
