Why Do Wet Floors Slip, But Wet Clothes Stick

The video explores how water affects surfaces differently, making some slippery and others sticky. It explains that friction is crucial for walking, but water reduces friction on floors, causing slips. Wet clothes stick due to water filling fabric pores, creating a vacuum and cohesion between water molecules. Rainproof clothing prevents water from entering, keeping you dry.

What causes surfaces to become slippery when wet?

• Water increases friction between surfaces.

• Water evaporates quickly.

• Water fills holes and reduces friction.

• Water creates a sticky layer.

How do slip-resistant shoes help prevent falls?

• They absorb water completely.

• They are made of waterproof material.

• They have a smooth surface.

• They allow water to escape, increasing friction.

Why do wet clothes tend to stick to the skin?

• They are made of non-porous material.

• They dry faster than expected.

• They repel water effectively.

• They create a vacuum by filling fabric pores.

What is the role of cohesion in wet clothes sticking to the skin?

• It breaks down water molecules.

• It attracts similar molecules together.

• It repels water molecules.

• It prevents water from entering the fabric.

How do rainproof clothes keep you dry?

• They absorb water quickly.

• They are made of cotton.

• They have large gaps for water to pass through.

• They prevent water from seeping in by having no big gaps.
