Review - Properties of water & Acids and Bases

Multiple Choice

What is the role of hydrogen bonds in water molecules?

• They increase the boiling point of water

• They hold water molecules together

• They create ionic bonds between water molecules

• They decrease the density of water

Multiple Choice

What role does cohesion play in the surface tension of water?

• It decreases surface tension by reducing the attraction between water molecules

• It increases surface tension by enhancing the attraction between water molecules

• It has no effect on surface tension

Multiple Choice

What is adhesion in the context of water properties?

• The attraction between water molecules only.

• The attraction between water molecules and different types of molecules or surfaces.

• The repulsion between water molecules and oil.

Multiple Choice

How does adhesion contribute to the process of capillary action in plants?

• It causes water molecules to stick to the sides of plant vessels, assisting in upward movement

• It decreases the surface tension of water, allowing easier flow

• It increases the boiling point of water, facilitating transpiration

• It has no role in capillary action
