Water Properties

Front

What is the universal solvent and why is water considered one?

Back

Water is known as the universal solvent because it can dissolve most substances due to its polar nature.

Front

What is the chemical formula for water?

Back

The chemical formula for water is H₂O.

Front

What is capillary action in relation to water?

Back

Capillary action is the ability of water to defy gravity and climb up a tube or narrow space due to adhesion and cohesion.

Front

Why do large bodies of water have a high heat capacity?

Back

Large bodies of water do not quickly fluctuate in temperature because water has a high heat capacity, meaning it can absorb a lot of heat without a significant change in temperature.

Front

What defines a polar molecule?

Back

A polar molecule is one that has an opposite electrical charge on each end, resulting in a dipole moment.

Front

What property of water allows it to have a high surface tension?

Back

The high surface tension of water is due to the cohesive forces between water molecules.

Front

How does water's density change when it freezes?

Back

Water expands and becomes less dense when it freezes, which is why ice floats on water.

Front

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

Back

Water's high specific heat helps regulate climate by absorbing and releasing heat slowly, moderating temperature changes.

Front

What role does water play in biological systems?

Back

Water is essential for life as it serves as a solvent, a medium for chemical reactions, and helps regulate temperature in organisms.

Front

What is the difference between adhesion and cohesion in water?

Back

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