The formula of the ideal gas law is: PV = nRT. where: P — Pressure, in pascal; V — Volume in cubic meters; n — Number of moles; T — Temperature in kelvin; and; R — Ideal gas constant. Remember to use consistent units! The value commonly used for R, 8.314... J/mol·K refers to the pressure measured exclusively in pascals.

The Ideal Gas Law and the Individual Gas Constant - R . The Ideal Gas Law - or Perfect Gas Law - relates pressure, temperature, and volume of an ideal or perfect gas . The Ideal Gas Law can be expressed with the Individual Gas Constant . p V = m R T (4) where. p = absolute pressure [N/m 2], [lb/ft 2] V = volume [m 3], [ft 3]
30 sty 2023 · The term \(\frac{pV}{nRT}\) is also called the compression factor and is a measure of the ideality of the gas. An ideal gas will always equal 1 when plugged into this equation. The greater it deviates from the number 1, the more it will behave like a real gas rather than an ideal.
The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions, although it has several limitations.
One pascal is a small pressure; in many cases, it is more convenient to use units of kilopascal (1 kPa = 1000 Pa) or bar (1 bar = 100,000 Pa). In the United States, pressure is often measured in pounds of force on an area of one square inch— pounds per square inch (psi) —for example, in car tires.

The SI unit of pressure is the pascal (Pa), with 1 Pa = 1 N/m 2, where N is the newton, a unit of force defined as 1 kg m/s 2. One pascal is a small pressure; in many cases, it is more convenient to use units of kilopascal (1 kPa = 1000 Pa) or bar (1 bar = 100,000 Pa).
