What is the equation for the Ideal Gas Law?

The Ideal Gas Law is a fundamental equation in thermodynamics that relates the pressure (P), volume (V), temperature (T), and amount of substance in moles (n) of an ideal gas. The equation is formulated as PV = nRT, where R represents the ideal gas constant. This relationship is crucial as it allows for the calculation of one property of the gas when the others are known, assuming the gas behaves ideally.

In the equation, pressure is measured in units such as atmospheres or pascals, volume in liters or cubic meters, temperature in Kelvin, and n is the number of moles of the gas. R, the ideal gas constant, has values depending on the units used, which typically is 0.0821 L·atm/(mol·K) or 8.314 J/(mol·K). This law is essential for understanding gas behavior under varying conditions and is widely utilized in various engineering and scientific applications.

The other choices presented are relevant to gas behavior but do not represent the complete relationship that describes the behavior of an ideal gas in all scenarios. The second choice, P1V1 = P2V2, is an expression of Boyle's Law, which applies to scenarios of gas
