Properties of Water

Front

What causes capillary action in water?

Back

Capillary action is caused by adhesion and cohesion.

Front

What type of bond is responsible for the attraction between water molecules?

Back

Hydrogen bonds.

Front

Why does ice float on water?

Back

Ice floats because, as water freezes, it expands and its density decreases.

Front

What property causes water droplets to take on a spherical shape?

Back

Cohesion.

Front

What is the term for water's attraction to other substances?

Back

Adhesion.

Front

Define cohesion in the context of water.

Back

Cohesion is the attraction between water molecules due to hydrogen bonding.

Front

Define adhesion in the context of water.

Back

Adhesion is the attraction between water molecules and other substances.

Front

What is surface tension and how is it related to water?

Back

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

Front

Explain why water has a high specific heat capacity.

Back

Water has a high specific heat capacity due to hydrogen bonding, which requires more energy to change its temperature.

Front

What is the significance of water's density being less in its solid form than in its liquid form?

Back

This property allows ice to float on water, providing insulation for aquatic life in cold environments.
