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

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.
