Properties of Water

Front

What is cohesion in the context of water?

Back

Cohesion is the attraction between molecules of the same substance, such as water molecules sticking together.

Front

What is adhesion in the context of water?

Back

Adhesion is the attraction between molecules of different substances, such as water molecules sticking to a surface.

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces without the assistance of external forces, crucial for water movement in plants.

Front

Why do water droplets take a spherical shape?

Back

Water droplets take a spherical shape due to cohesion, as water molecules are attracted to each other.

Front

What role does cohesion play in water's properties?

Back

Cohesion contributes to water's surface tension, allowing it to form droplets and enabling small objects to float on its surface.

Front

How does adhesion benefit plants?

Back

Adhesion helps water stick to the surfaces of plant cells, aiding in the movement of water from roots to leaves.

Front

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

Back

Water's high specific heat allows it to absorb and retain heat, helping to regulate temperature in the environment.

Front

What is the relationship between temperature and water density?

Back

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

Front

What is the importance of ice floating on water?

Back

Ice floating on water insulates the water below, providing a habitat for aquatic life during cold weather.

Front

What is solubility in relation to water?

Back

Solubility is the ability of a substance to dissolve in water, making water a universal solvent.
