Water Properties

Front

What is surface tension?

Back

Surface tension is the cohesive force between liquid molecules at the surface of a liquid, which allows it to resist external force.

Front

What causes surface tension in water?

Back

Surface tension in water is caused by the cohesion of water molecules, which are attracted to each other.

Front

What is water's super solvency?

Back

Water's super solvency refers to its ability to dissolve a wide variety of substances due to its polar nature.

Front

Why is water considered a polar molecule?

Back

Water is considered a polar molecule because it has a partial positive charge on one side (hydrogens) and a partial negative charge on the other side (oxygen).

Front

What are hydrogen bonds?

Back

Hydrogen bonds are weak attractions between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom.

Front

What is the significance of hydrogen bonds in water?

Back

Hydrogen bonds give water its unique properties, such as high heat capacity, cohesion, and adhesion.

Front

What does high heat capacity mean?

Back

High heat capacity means that a substance can absorb a lot of heat without a significant change in temperature.

Front

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

Back

Water's high heat capacity helps regulate temperature in organisms and environments, providing stability.

Front

What is the role of water in cooling the body through sweating?

Back

When we sweat, the evaporation of water from the skin surface absorbs heat, cooling the body.

Front

What is cohesion in the context of water?

Back

Cohesion is the attraction between water molecules, which allows them to stick together.
