Will P., Ian A., Luana R., Jack H. Boyle’s Law Will P., Ian A., Luana R., Jack H.

WHat Is It? Boyle’s law states that the volume of a given mass of gas (V) is inversely proportional to its absolute pressure (P), provided the temperature of the gas (T) remains constant. More volume equals less pressure. Boyle’s law is the relationship between pressure and volume. This is an inverse mathematical relationship, as one quantity goes up in the value, the other goes down.
