Properties of Water

Front

What is a polar molecule?

Back

A molecule that has a partial positive charge on one end and a partial negative charge on the other end, leading to an uneven distribution of charge.

Front

What property of water allows it to have a high surface tension?

Back

Cohesion, which is the attraction between water molecules.

Front

What is adhesion in the context of water?

Back

The attraction between water molecules and other substances.

Front

What is the significance of hydrogen bonds in water?

Back

Hydrogen bonds are responsible for many of water's unique properties, including its high boiling point and surface tension.

Front

What is density in relation to water?

Back

Density is the mass per unit volume of water; ice is less dense than liquid water, which is why it floats.

Front

What is capillary action?

Back

The ability of water to flow in narrow spaces against gravity, due to adhesion and cohesion.

Front

What is the term for the attraction between water molecules?

Back

Cohesion.

Front

How does temperature affect the density of water?

Back

As water cools, it becomes denser until it reaches 4°C; below this temperature, it expands and becomes less dense.

Front

What is the role of water as a solvent?

Back

Water can dissolve many substances, making it an excellent solvent for chemical reactions.

Front

What is surface tension?

Back

The elastic-like force at the surface of water that makes it difficult to break through, caused by cohesive forces.
