Ideal Gas Law
The equation of state relating pressure, volume, temperature, and quantity of an ideal gas composed of non-interacting point particles.
Governing formula
P V = n R T = N kB T
SI unit
Pa·m³ = J
In depth
Combines Boyle's, Charles's, Gay-Lussac's, and Avogadro's laws. Accurately describes real gases at low pressures and high temperatures.
Examples in the real world
Calculating pressure rise inside a sealed car tire as road friction heats the air inside from 20°C to 50°C.
