What principle does the Ideal Gas Law incorporate that distinguishes it from Boyle's and Charles' Laws?

It includes a variable for mass.
It accounts for pressure, volume, and temperature together.
It applies to solids as well as gases.
It is limited to low-temperature scenarios.

The correct answer is: It accounts for pressure, volume, and temperature together.

The Ideal Gas Law incorporates a principle that accounts for pressure, volume, and temperature together, which distinguishes it from Boyle's and Charles' Laws. While Boyle's Law relates pressure and volume at constant temperature, and Charles' Law relates volume and temperature at constant pressure, the Ideal Gas Law combines these relationships into a single equation: $PV = nRT$. This equation integrates the three fundamental properties of gas behavior, as well as the amount of gas present (in terms of moles) and the universal gas constant. This integrated approach provides a comprehensive understanding of how gases behave under varying conditions, making it a more encompassing model of gas behavior than the individual laws.
