Boyle's Law — Science definition
At constant temperature, the pressure and volume of a fixed amount of gas are inversely proportional: P₁V₁ = P₂V₂.

In use
Boyle's Law freezes the temperature and pins down the relationship between pressure and volume: they are inversely proportional.

Questions using boyle's law
Problem 1
Boyle's Law states that at constant temperature, the pressure and volume of a gas are…
- completely unrelated
- inversely proportional
- directly proportional
- always equal
Answer and explanation
inversely proportional
Boyle's Law: as volume decreases, pressure increases in inverse proportion, so P₁V₁ = P₂V₂.
Problem 2
At constant temperature, Boyle's Law relates which two quantities?
- pressure and volume
- volume and moles
- pressure and temperature
- temperature and volume
Answer and explanation
pressure and volume
Boyle's Law connects pressure and volume (inversely) at constant temperature.
