What is the ideal gas law equation?

The ideal gas law is a fundamental equation in thermodynamics that describes the relationship between pressure, volume, temperature, and the number of moles of a gas. The correct formula, PV=nRT, encompasses these variables cohesively.

In this equation:

• P stands for the pressure of the gas,

• V represents the volume of the gas,

• n is the number of moles of the gas,

• R is the ideal gas constant, and

• T is the absolute temperature in Kelvin.

This relationship shows that for an ideal gas, the pressure and volume are directly proportional to the number of moles and the temperature when all other factors are held constant. It is valuable for predicting how a gas will behave under varying conditions, making it essential for applications in various engineering fields, including power engineering.

The other options listed do not accurately represent the ideal gas law. They either rearranged the terms incorrectly or included operations that do not logically apply to the relationships among pressure, volume, temperature, and number of moles as described by the ideal gas behavior. Understanding the correct formulation allows for better analysis and problem-solving in applications involving gases.
