Thomas Graham (physicist)

Thomas Graham was a 19th-century Scottish chemist and physicist known for his work on the diffusion of gases. He formulated Graham's Law, which states that the rate at which a gas diffuses is inversely proportional to the square root of its molar mass. This means lighter gases diffuse faster than heavier ones. Graham’s research laid the groundwork for understanding gas behaviors, influencing fields like chemistry and physics. Additionally, he contributed to studies on effusion, where gases escape through small openings, further enhancing our knowledge of gas properties and behaviors. Graham's work remains fundamental in various scientific applications today.
