The Unique Properties of Water

Front

What is cohesion in the context of water?

Back

Cohesion is the property of water that allows water molecules to stick to each other, resulting in surface tension.

Front

What is adhesion in the context of water?

Back

Adhesion is the property of water that allows it to stick to other substances, which is important for processes like capillary action.

Front

What is the molecular composition of a water molecule?

Back

A water molecule is composed of 2 Hydrogen atoms and 1 Oxygen atom (H2O).

Front

At what temperature does water freeze?

Back

Water freezes at 0°C.

Front

What is the boiling point of water?

Back

The boiling point of water is 100°C at standard atmospheric pressure.

Front

Why is water considered a universal solvent?

Back

Water is considered a universal solvent because it can dissolve many substances due to its polar nature.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of a substance by 1°C. Water has a high specific heat capacity.

Front

How does water's high specific heat capacity benefit living organisms?

Back

Water's high specific heat capacity helps regulate temperature in organisms and environments, preventing drastic temperature changes.

Front

What is surface tension in water?

Back

Surface tension is the cohesive force at the surface of water that makes it behave like a stretched elastic membrane.

Front

What role does water play in temperature regulation in the human body?

Back

Water helps regulate body temperature through processes like sweating and evaporation.
