What equation represents the Ideal Gas Law?

The Ideal Gas Law is represented by the equation ( PV = nRT ). This equation describes the relationship between pressure (P), volume (V), the amount of substance in moles (n), the ideal gas constant (R), and temperature (T) in Kelvin.

In the equation, pressure (P) is directly proportional to the number of moles of gas (n) and the temperature (T), while inversely proportional to the volume (V). This means that for a fixed amount of gas at a specified temperature, if you increase the volume, the pressure will decrease, and vice versa.

This relationship allows us to predict how a gas behaves under various conditions of temperature and pressure. Understanding this law is fundamental in chemistry, particularly in fields involving gas reactions, standard conditions, and thermodynamics.

The other forms mentioned do not accurately express the complete relationships defined by the Ideal Gas Law. For example, option A only accounts for pressure and moles without explicitly linking volume and temperature; option B introduces an incorrect combination of pressure and volume; and option D suggests a relationship between volume and moles, missing key components like pressure and temperature. Thus, ( PV = nRT ) is the only correct representation of the Ideal
