Common questions
What is the Ideal Gas Law formula?
Ideal Gas Law is written PV = nRT. Equation of state for ideal gas. It belongs to Thermodynamics, under Kinetic Theory.
What are the units in PV = nRT?
In SI units, P is pressure, measured in kg/(m·s²); V is volume, measured in m³; n is moles, measured in mol; R is gas constant, measured in kg·m²/(s²·mol·K); T is temperature, measured in K.
How is the Ideal Gas Law formula derived?
Combines Boyle, Charles, and Avogadro laws. The result is PV = nRT.
