Properties of Water

Front

What makes water a polar molecule?

Back

The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.

Front

Which property of water allows frozen water to float on liquid water?

Back

Water expands when it freezes, making ice less dense than liquid water.

Front

How many hydrogen atoms are present in a single water molecule?

Back

2

Front

What type of bond forms between ions?

Back

Ionic bonds.

Front

What term describes the attraction of water molecules to other substances?

Back

Adhesion.

Front

What is cohesion in the context of water?

Back

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

Front

What is surface tension in water?

Back

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

Front

What is capillary action?

Back

Capillary action is the ability of water to flow in narrow spaces against gravity, due to adhesion and cohesion.

Front

Why does water have a high specific heat capacity?

Back

Water can absorb a lot of heat before its temperature changes, due to hydrogen bonding.

Front

What is the significance of water's solvent properties?

Back

Water is known as the 'universal solvent' because it can dissolve many substances, facilitating chemical reactions.
