Unit 2 AOS 1 - Properties of Water Quiz (1)

What type of bond holds the hydrogen and oxygen atoms together in a water molecule?

• Metallic bond

• Ionic bond

• Covalent bond

• Hydrogen bond

Explain how hydrogen bonding in water contributes to its unique properties.

• Hydrogen bonding has no effect on the unique properties of water

• Hydrogen bonding creates cohesion, adhesion, high surface tension, and the ability to moderate temperature.

• Hydrogen bonding leads to low surface tension in water

• Hydrogen bonding creates repulsion between water molecules

Define cohesion and give an example of how it is exhibited in water.

• Water molecules repelling each other due to hydrogen bonding

• Water molecules attracting other substances due to hydrogen bonding

• Water molecules sticking together due to hydrogen bonding

• Water molecules breaking apart due to hydrogen bonding

How does adhesion of water contribute to the movement of water in plants?

• Adhesion of water allows it to move up the plant's vascular system

• Adhesion of water has no impact on the movement of water in plants

• Adhesion of water only affects the movement of water in animals

• Adhesion of water causes it to move down the plant's vascular system

What causes the surface tension of water and how does it affect the behavior of water droplets?

• The presence of air bubbles in the water

• Adhesive forces between water molecules

• Cohesive forces between water molecules

• The temperature of the water

Explain the concept of specific heat capacity and why water has a high specific heat capacity.

• Water has a high specific heat capacity due to its hydrogen bonding.

• Water has a high specific heat capacity due to its low boiling point.

• Water has a high specific heat capacity due to its lack of hydrogen bonding.

• Water has a high specific heat capacity due to its high density.

How does water's high specific heat capacity contribute to its role in moderating temperature on Earth?

• It helps water to absorb and release large amounts of heat with minimal temperature change.

• It leads to water evaporating quickly

• It makes water unable to absorb heat

• It causes water to freeze at a higher temperature

Why is water considered a universal solvent and what types of substances can it dissolve?

• Water is not a universal solvent and it can only dissolve non-polar compounds.

• Water is a universal solvent but it can only dissolve metals and metalloids.

• Water is not a universal solvent and it can only dissolve organic compounds.

• Water is considered a universal solvent and it can dissolve a wide range of substances including polar and ionic compounds.
