Properties of Water

Front

What is the molecular composition of water?

Back

Water is composed of two hydrogen atoms and one oxygen atom (H2O).

Front

What property of water allows small insects to walk on its surface?

Back

The property is surface tension, which is caused by hydrogen bonds between water molecules.

Front

What is the term for water's ability to dissolve many substances?

Back

Universal Solvent.

Front

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

Back

Water can absorb a lot of heat without a significant change in temperature due to hydrogen bonding.

Front

What happens to water when it freezes?

Back

Water expands when it freezes, making ice less dense than liquid water.

Front

What is cohesion in relation to water?

Back

Cohesion is the attraction between water molecules, which allows for surface tension.

Front

What is adhesion in relation to water?

Back

Adhesion is the attraction between water molecules and other substances, allowing water to climb up surfaces.

Front

How does water's high specific heat benefit the environment?

Back

It helps regulate temperatures in the environment, preventing extreme temperature fluctuations.

Front

What is the significance of water being a polar molecule?

Back

Water's polarity allows it to form hydrogen bonds, which are crucial for many of its unique properties.

Front

What is the effect of water's high heat of vaporization?

Back

It allows organisms to cool down through processes like sweating and transpiration.
