Properties of Water

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 from roots to leaves in plants.

What is Surface Tension?

Back

Surface tension is the tightness across the surface of water that allows objects, like paper clips, to float.

What does Cohesive mean in relation to water?

Back

Cohesive means that water molecules stick to each other due to hydrogen bonding.

Front

What does Adhesive mean in relation to water?

Back

Adhesive means that water molecules stick to other surfaces, allowing water to climb up a straw.

Front

What is Cohesion?

Back

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

Front

What is Adhesion?

Back

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

Front

Why does ice float on water?

Back

Ice floats on water because it is less dense than liquid water due to the arrangement of water molecules in a solid state.

Front

What is Polarity in water molecules?

Back

Polarity refers to the distribution of electrical charge over the atoms joined by the bond, making water molecules have a positive and a negative end.

How does temperature affect the density of water?

Back

As water cools, it becomes denser until it reaches 4°C; below this temperature, it becomes less dense, causing ice to float.

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

Back

Water's high specific heat means it can absorb a lot of heat without a significant change in temperature, helping regulate climate.
