# Ideal gas law calculator

Ideal gas law states that product of a pressure and volume is proportional to the product of temperature and amount of gas. The coefficient of proportionality is called ideal gas constant and does not depend on the type of the gas. Ideal gas law applies to gases in conditions where molecular volume and inter-molecular forces are negligible. This law is a generalization of the combined gas law over different types of gases. Ideal gas law could also be derived from the kinetic theory. Ideal gas law wiki article
