in osmosis the water goes through the semi permeable membrane for example, to make a equilibriam. why does it have to be equal?
ReplyDeleteIt reaches an equalibrium because molecules are always moving - sometimes slowly (like in a solid) or sometimes very fast like in a gas. Over time theings even out and beccome eual on both sides - it reaches an equalibrium. Its kind of like putting a bunch of blue beads in a jar, and then adding red ones on top. If you start to shake the jar (make the beads move) they will start to mix (difuse). Over time the will reach an equalibrium.
