Which equation represents Boyle's Law?

Boyle's Law states that the pressure (P) of a gas is inversely proportional to its volume (V) when the temperature (T) and the amount of gas (n) are held constant. This relationship can be mathematically expressed with the equation P1V1 = P2V2, which indicates that as the volume of the gas decreases, its pressure increases, and vice versa, provided that the number of moles and temperature remain unchanged.

In this equation, P1 and V1 refer to the initial pressure and volume of the gas, while P2 and V2 refer to the pressure and volume after a change has occurred. This fundamental principle is key in understanding how gases behave under varying conditions, which is a basic tenet of gas laws in chemistry.

The other equations pertain to different gas laws or principles. For instance, the equation P1/T1 = P2/T2 relates to Charles's Law, which describes the direct relationship between the temperature and volume of a gas. V1/T1 = V2/T2 also pertains to Charles's Law, expressing the relationship between volume and temperature at constant pressure. Lastly, the equation PV = nRT is the ideal gas law, which combines all gas relationships but
