Answer:
The answer is osmosis
Step-by-step explanation:
Osmosis:
Osmosis is the type of diffusion that involves the movement of water molecules. It is the movement of water molecules from an area of high water (or low solute) concentration to that of low water (or high solute) concentration through a semi-permeable membrane.
As the water moves to the solution of the low water concentration, the volume of water in the second solution increases until equilibrium stage at which both solutions have equal concentration of water.
