Properties of Water Review

Front

What is Cohesion?

Back

Cohesion is the attraction between water molecules, causing them to stick together.

Front

What is Adhesion?

Back

Adhesion is the attraction between water molecules and other substances.

Front

What causes surface tension in water?

Back

Surface tension is caused by strong cohesion between water molecules.

Front

How does water's polarity affect its ability to dissolve substances?

Back

Water's polarity allows it to dissolve many substances, making it a universal solvent.

Front

What is the significance of water's high specific heat?

Back

Water's high specific heat helps regulate temperature in the environment and in living organisms.

Front

Explain the concept of capillary action.

Back

Capillary action is the ability of water to flow in narrow spaces against gravity, due to adhesion and cohesion.

Front

What is the role of water in biological systems?

Back

Water is essential for life, serving as a solvent, a temperature buffer, and a medium for biochemical reactions.

Front

Define the term 'polarity' in relation to water molecules.

Back

Polarity refers to the distribution of electrical charge in water molecules, leading to partial positive and negative charges.

Front

What is the difference between cohesion and adhesion?

Back

Cohesion is the attraction between water molecules, while adhesion is the attraction between water molecules and other substances.

Front

How does temperature affect the density of water?

Back

Water is most dense at 4°C; as it freezes, it becomes less dense, allowing ice to float.
