<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> What is diffusion?

Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> The phenomenon of intermixing particles of one kind with another kind is called diffusion. For example, the smell of food particularly of fish being cooked in the kitchen spreads in the lobby and even in different rooms because of diffusion.
