What is the Ideal Gas Law formula?

The Ideal Gas Law formula is expressed as PV = nRT. This equation links several fundamental properties of gases: pressure (P), volume (V), the number of moles of gas (n), the ideal gas constant (R), and temperature (T) in Kelvin.

In this formula, pressure and volume are directly linked to the amount of substance and temperature, illustrating how gases behave under various conditions. It demonstrates that for a given amount of gas at a constant temperature, an increase in volume will result in a decrease in pressure and vice versa.

This law is essential in various scientific applications, including thermodynamics and physical chemistry, as it allows for the calculation and prediction of the behavior of gases. The other options provided do not correctly represent the relationship defined by the Ideal Gas Law, which is crucial for accurately understanding gas behavior in scientific contexts.
