The Ideal Gas Law is a fundamental equation in chemistry that describes the behavior of an ideal gas. It relates the pressure, volume, temperature, and number of moles of a gas.
The equation for the Ideal Gas Law is: , where is the pressure, is the volume, is the number of moles, is the ideal gas constant, and is the temperature in Kelvin.
To identify the correct equation, recognize that the Ideal Gas Law combines these variables into a single equation that can be used to solve for any one of the variables if the others are known.
The equation is a rearrangement of the Ideal Gas Law, solving for volume, but the standard form is .
The other equations provided, and , represent Boyle's Law and a general proportionality constant, respectively, and are not the Ideal Gas Law.
