Diffusion in gases
Diffusion in gases is the process where molecules spread out from an area of high concentration to an area of lower concentration, driven by their random motion. As gas particles move constantly in all directions, they collide and disperse, gradually mixing with surrounding air until evenly distributed. This natural tendency helps gases mix smoothly without external forces, and the rate of diffusion depends on factors such as temperature, pressure, and the size of the molecules involved. Essentially, diffusion is how gases naturally blend together over time through their kinetic activity.
