Answer 2

$\huge\boxed{\fcolorbox{red}{yellow}{ANSWER}}$ EXAMPLES ARE :$<font color="Red">$1)If we write something on a black board and leave it uncleaned for a period say 10 - 15 days, we will find that it becomes quite difficult to clean the blackboard afterwards. This is due to the fact that some of the particles of chalk have diffused into surface of the board.

2) If two metals blocks are bound together tightly and kept undisturbed for a few years, then the particles of one metal are found to have diffused into the other metal.$<marquee><font color="green"><h1>FOLLOW ME AND MARK AS BRAINLIEST TOO </marquee>$
