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
- 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.
