Graham’s Law
Graham's Law states that the rate at which a gas escapes or diffuses is inversely proportional to the square root of its molar mass. In simpler terms, lighter gases move faster than heavier ones. For example, if you release a helium balloon and a balloon filled with a heavier gas like argon, the helium will rise and disperse more quickly. This principle helps explain various natural phenomena, such as why certain gases can travel through air more rapidly, and is fundamental in fields like chemistry and physics.

Graham's Law states that the rate at which a gas diffuses (spreads out) is inversely proportional to the square root of its molar mass. This means lighter gases will diffuse faster than heavier ones. For example, helium, which is lighter than oxygen, will spread out more quickly in a room. In practical terms, this principle helps explain why certain gases disperse faster than others, influencing various applications like air quality and the behavior of gases in different environments.
