The Ideal Gas Equation The ideal gas equation is: pV = nRT On the whole, this is an easy equation to remember and use. The problems lie almost entirely in the units. I am assuming below that you are working in strict SI units (as you will be if you are doing a UK-based exam, for example). Exploring the various terms Pressure, p What is Ideal Gas Law? The ideal gas law, also known as the general gas equation, is an equation of the state of a hypothetical ideal gas. Although the ideal gas law has several limitations, it is a good approximation of the behaviour of many gases under many conditions. When dealing with gas, a famous equation was used to relate all of the factors needed in order to solve a gas problem. This equation is known as the Ideal Gas Equation. As we have always known, anything ideal does not exist. In this issue, two well-known assumptions should have been made beforehand: Explore the Ideal Gas Law (PV = nRT), the equation that unites pressure, volume, temperature, and moles of gas. Learn how this powerful formula predicts gas behavior.
