Front

What is the chemical formula of water?

Back

H2O, which consists of two hydrogen atoms and one oxygen atom.

Front

What is capillary action in relation to water?

Back

It is the ability of water to move through narrow spaces, such as from roots to leaves in plants.

Front

Why is water known as a universal solvent?

Back

Because it can dissolve most substances.

Front

What property of water allows it to dissolve many substances?

Back

Water is polar.

Front

What causes water droplets to take a spherical shape?

Back

Cohesion among water molecules.

Front

Define cohesion in the context of water molecules.

Back

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

Front

What is adhesion and how does it relate to water?

Back

Adhesion is the attraction between water molecules and other substances, which helps in capillary action.

Front

Explain the significance of water's high specific heat capacity.

Back

It allows water to absorb and retain heat, stabilizing temperatures in the environment.

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

How does the density of water change when it freezes?

Back

Water expands and becomes less dense when it freezes, causing ice to float.
