The Ideal Gas Law (PV = nRT)

The ideal gas law is the equation of state of a hypothetical ideal gas. It is a good approximation of the behavior of many gases under many conditions.

P × V = n × R × T
  • P (Pressure): Measured in Pascals (Pa).
  • V (Volume): Measured in cubic meters (m³).
  • n (Moles): The amount of substance (mol).
  • R (Gas Constant): The universal gas constant, ≈ 8.314 J/(mol·K).
  • T (Temperature): The absolute temperature in Kelvin (K).
