Science
Boyle's law.
Definition
Boyle's law states that the pressure of a gas is inversely proportional to its volume when temperature and the amount of gas are held constant. As volume decreases, pressure increases, and vice versa.
Examples
Real-world.
- 1 Squeezing a sealed syringe decreases the volume and increases the air pressure inside
- 2 A diver's lungs compress as they descend deeper underwater due to increasing water pressure
- 3 A balloon expands when taken to higher altitude where atmospheric pressure is lower
Key Fact
P₁V₁ = P₂V₂ (at constant temperature and moles)
