8.6C - Behavior of Water

Front

What is cohesion in water molecules?

Back

Cohesion is the property of water molecules that causes them to be strongly attracted to each other, resulting in high surface tension.

Front

What is surface tension?

Back

Surface tension is the elastic-like force existing on the surface of a liquid, caused by the attraction between water molecules.

Front

What is capillary action?

Back

Capillary action is the ability of water to defy gravity and climb up narrow tubes or spaces due to cohesion and adhesion.

Front

What is adhesion in water molecules?

Back

Adhesion is the property of water molecules that causes them to be attracted to other substances, such as the walls of a tube.

Front

How does temperature affect the density of water?

Back

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

Front

What is the universal solvent?

Back

Water is known as the universal solvent because it can dissolve more substances than any other liquid.

Front

What role does water play in plant transport?

Back

Water is transported from the roots to the leaves through the xylem, utilizing processes like cohesion, adhesion, and capillary action.

Front

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 to regulate climate and body temperature.

Front

What is the 'stickiness' of water?

Back

The 'stickiness' of water refers to its cohesion, which allows it to form droplets and resist external forces.

Front

Why do some insects walk on water?

Back

Some insects can walk on water due to surface tension, which is created by the cohesive forces between water molecules.
