Meaning and Definition
A physical law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
A foundational principle in thermodynamics and gas chemistry, named after the 17th-century scientist Robert Boyle. It describes the predictable relationship between the pressure and volume of a confined gas, often summarized as P ∝ 1/V (pressure times volume equals a constant). It's a cornerstone concept in understanding gas behaviour.

FAQ
Frequently Asked Questions
It is named after the Anglo-Irish natural philosopher Robert Boyle, who published it in 1662.
P₁V₁ = P₂V₂ or PV = k, where P is pressure, V is volume, and k is a constant for a given mass of gas at constant temperature.
It is an ideal gas law and applies perfectly only to ideal gases. However, it provides a very good approximation for real gases under many ordinary conditions of temperature and pressure.
It is applied in designing syringes, scuba diving equipment (to calculate air consumption at depth), internal combustion engines, and in understanding the mechanics of breathing in human lungs.
A physical law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
Boyle's law is usually academic / scientific / technical in register.
Boyle's law: in British English it is pronounced /ˈbɔɪlz lɔː/, and in American English it is pronounced /ˈboʊlz lɑː/ or /ˈbɔɪlz lɑː/. Tap the audio buttons above to hear it.

Mnemonic
Think of a syringe: when you push the plunger down (decrease volume), it gets harder to push (pressure increases). Boyle's Law explains this: as volume goes down, pressure goes up, and vice versa.
Conceptual Metaphor
A seesaw relationship: Pressure and Volume sit on opposite ends. When one goes up, the other must come down, provided temperature stays seated in the middle.
