Hey mate...
⏺The answer may be osmosis or diffusion.

⏺As in both cases the movement of particles takes place.

⏺But in diffusion all three states of mater can move and in osmosis only water movement takes place.

⏺Also in diffusion there is not semi permeable membrane but in osmosis there is a semi permeable membrane.
