Properties of Water Quiz

Which of the following is NOT a special property of water?

• Cohesive/Adhesive Nature

• Ability to moderate temperature

• Expansion upon freezing

• Induces chemical reactions

Answer explanation

The correct choice is 'Induces chemical reactions' as it is NOT a special property of water. Water does not induce chemical reactions, unlike its other special properties.

What property of water allows it to dissolve many different substances?

• Expansion upon freezing

• Versatility as a solvent

• Cohesive/Adhesive Nature

• Ability to moderate temperature

Answer explanation

Water's versatility as a solvent allows it to dissolve many different substances due to its ability to form hydrogen bonds with a wide range of molecules.

What type of bond is shown in the diagram?

• Ionic bond

• Covalent bond

• Hydrogen bond

• Metallic bond

Answer explanation

The correct type of bond shown in the diagram is a Hydrogen bond, which is a weak type of bond formed between a hydrogen atom and an electronegative atom like oxygen or nitrogen.

What is cohesion as defined in the context of water molecules?

• The repulsion between molecules of different substances.

• The attraction between molecules of the same substance.

• The process by which water boils and becomes vapor.

• The process by which water freezes and becomes ice.

Answer explanation

Cohesion in the context of water molecules refers to the attraction between molecules of the same substance, which causes them to stick together.

What property of water allows it to form a type of "skin" on its surface strong enough to support some objects?

• Viscosity

• Opacity

• Surface tension

• Density

Answer explanation

Water forms a 'skin' on its surface due to surface tension, which is a property that allows the molecules at the surface to stick together and create a strong cohesive force.

Which type of bonds in water molecules contribute to high surface tension?

• Ionic bonds

• Covalent bonds

• Hydrogen bonds

• Metallic bonds

Answer explanation

Hydrogen bonds in water molecules contribute to high surface tension due to their strong intermolecular forces that create a cohesive force at the surface.

What does adhesion cause water to do?

• Evaporate quickly

• Stick to other polar substances

• Freeze at higher temperatures

• Become less dense when heated

Answer explanation

Adhesion causes water to stick to other polar substances, allowing it to form hydrogen bonds with other molecules.

What does the term "cohesion" refer to in the context of the diagram?

• The attraction between water molecules and other substances

• The attraction between water molecules and air

• The attraction between water molecules themselves

• The repulsion between water molecules and other substances

Answer explanation

The term 'cohesion' refers to the attraction between water molecules themselves, as shown in the diagram.

What does the term "adhesion" refer to as illustrated in the diagram?

• The attraction between water molecules and other substances

• The attraction between water molecules and air

• The attraction between water molecules themselves

• The repulsion between water molecules and other substances

Answer explanation

The term 'adhesion' refers to the attraction between water molecules and other substances, as illustrated in the diagram.

What happens to water upon freezing?

• It contracts and becomes denser than liquid water.

• It expands and becomes less dense than liquid water.

• It maintains the same density as liquid water.

• It evaporates and becomes a gas.

Answer explanation

When water freezes, it expands and becomes less dense than liquid water, which is why ice floats on water.
