How osmosis is different from diffusion

Diffusion:

Movement always works down the concentration gradient.

It does not Requires membrane.

It can be applied to liquids, solids, and gases.

Increase system entrophy

Osmosis:

Movement always works up the concentration gradient.

Requires membrane.

Only applicable to liquids.

Decreases system entrophy

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
