What charge does the oxygen atom in a polar water molecule have?

Back

The oxygen atom in a polar water molecule has a slight negative charge.

Front

What is cohesion in relation to water molecules?

Back

Cohesion is the property of water molecules that allows them to stick together, forming clumps.

Front

What is surface tension in water?

Back

Surface tension is the tightness of the surface of water caused by the attraction between polar molecules.

Front

What is specific heat?

Back

Specific heat is the amount of heat needed to increase the temperature of a substance by 1 degree Celsius.

What is adhesion in relation to water?

Back

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

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces without the assistance of external forces.

Front

Why is water known as a universal solvent?

Back

Water is known as a universal solvent because it can dissolve many substances due to its polar nature.

Front

What is the significance of water's high specific heat?

Back

Water's high specific heat helps regulate temperature in the environment and in living organisms.

Front

How does water's polarity affect its properties?

Back

Water's polarity leads to unique properties such as cohesion, adhesion, and high surface tension.
