Water properties

Front

What is surface tension?

Back

Surface tension is the cohesive force between water molecules at the surface, allowing it to resist external force.

Front

What is cohesion in water molecules?

Back

Cohesion is the property of water molecules that allows them to stick to each other due to hydrogen bonding.

Front

What is adhesion in water molecules?

Back

Adhesion is the property of water molecules that allows them to stick to other substances.

Front

What does it mean that water has a high specific heat?

Back

It means that water requires a lot of energy to change its temperature, which helps regulate climate.

Front

How do large bodies of water affect climate?

Back

They absorb heat in the summer and slowly release it in the winter, moderating temperature extremes.

Front

What is the significance of water's polarity?

Back

Polarity allows water to dissolve many substances, making it a universal solvent.

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces without the assistance of external forces, due to adhesion and cohesion.

Front

What is the role of hydrogen bonds in water?

Back

Hydrogen bonds are weak attractions between water molecules that contribute to water's unique properties.

Front

What is the difference between cohesion and adhesion?

Back

Cohesion refers to water molecules sticking to each other, while adhesion refers to water molecules sticking to other substances.

Front

What is the effect of temperature on water density?

Back

Water is most dense at 4°C; as it freezes, it becomes less dense, allowing ice to float.
