Answer
False
Explanation
Diffusion is a phenomenon whereby particles spread out evenly through an available space, moving from a region where they are densely concentrated to one where they are less concentrated. They do this spontaneously, continually, and in all media—solids, liquids, and gases, not just in liquids. An effective example of diffusion in gases is the dispersal of a spray perfume throughout a room. In solids, you can observe diffusion at play when a cube of sugar dissolves uniformly in a hot cup of coffee. Hence, it's incorrect to assert that diffusion happens only in liquids.
