How did an early understanding of gases lead to a better understanding of the antom?

Early studies of gases, particularly through experiments by scientists like Robert Boyle and Jacques Charles, revealed the relationship between pressure, volume, and temperature, laying the groundwork for the kinetic molecular theory. This theory posited that gases are composed of tiny particles in constant motion, which helped shift the focus from macroscopic properties to the microscopic behavior of matter. As researchers explored gas laws and molecular interactions, they began to conceptualize atoms as the fundamental building blocks of matter, thus enhancing the overall understanding of atomic structure and behavior. This progression ultimately contributed to the development of modern atomic theory.
