A. J. Van der Waals

A. J. Van der Waals was a Dutch scientist who made important contributions to understanding how molecules and atoms interact. He developed the Van der Waals equation, which improves upon ideal gas laws by accounting for the size of molecules and the attractions between them. This helps explain real-world behaviors of gases, such as liquefaction and condensation, more accurately. His work provided foundational insights into molecular forces, influencing physics and chemistry, and helping scientists better grasp the nature of matter at a microscopic level.
