What is the process of osmosis?

Answer 1

Osmosis is the diffusion of water where molecules of water move passively (without energy) from high concentration to low concentration.

A good example would be the way water rushes into a sponge, when a dry sponge is placed in a pan of water. Water fills the empty spaces of the sponge until the concentration in and out of the sponge is normalized.

Here is a video which describes how osmosis impacts onion cells placed into tap water and then into a salt water solution.

Osmosis is the movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration, in order to equalize the concentration of solute on both sides of the membrane.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
