Ideal Gas Law

The ideal gas law is a fundamental principle in physics and chemistry that describes the behavior of an ideal gas. An ideal gas is a theoretical gas composed of a large number of molecules that have negligible volume and exert no intermolecular forces. The ideal gas law is expressed by the equation:

PV = nRT

• P = pressure of the gas (in Pascals)
• V = volume of the gas (in cubic meters)
• n = number of moles of the gas
• R = ideal gas constant (8.314 J/(mol*K))
• T = temperature of the gas (in Kelvins)

The ideal gas law can be used to calculate the pressure, volume, temperature, or number of moles of an ideal gas when the other three variables are known.
