What is the role of the outer layer of a diaper?

• To prevent leakage

• To absorb moisture

How does sodium polyacrylate absorb water?

• By forming a gel-like substance

• By dissolving in water

• By evaporating water

• By breaking down into smaller molecules

What scientific principle allows diapers to hold a large amount of liquid?

• Osmosis

• Capillary action

• Polymer absorption

• Diffusion

Which experiment can demonstrate the absorbency of a diaper?

• Measuring the weight before and after adding water
