If you open a bottle of perfume after a period of time the people on the opposite side of the room will be able to smell it due to what process?

When you open a bottle of perfume, the fragrance molecules evaporate into the air, a process known as diffusion. These molecules disperse from an area of high concentration (inside the bottle) to areas of lower concentration (the surrounding air), allowing people on the opposite side of the room to detect the scent. This movement of particles continues until equilibrium is reached, enabling the aroma to travel across the space.
