In Boyle's Law, which variable is held constant?

Explanation:
Boyle's Law shows how pressure and volume relate when the temperature stays the same. With a fixed amount of gas and constant temperature, the product P×V stays constant, so pressure and volume move inversely: as volume decreases, pressure increases proportionally. This is why temperature is the variable held constant in Boyle's Law. If temperature weren’t constant, the simple inverse relationship wouldn’t apply, and you’d need other gas laws to describe the behavior.
