Properties of Water

Front

What is hydrogen bonding?

Back

A weak attraction between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom.

Front

What is cohesive behavior in water?

Back

The tendency of water molecules to stick to each other due to hydrogen bonding, which allows for phenomena like surface tension.

Front

What is adhesive strength in water?

Back

The ability of water molecules to stick to other substances, which helps in processes like capillarity.

Front

What is specific heat?

Back

The amount of heat required to raise the temperature of a substance by one degree Celsius; water has a high specific heat.

Front

What is heat capacity?

Back

The ability of a substance to absorb heat; water has a high heat capacity, allowing it to moderate temperature changes.

Front

What happens to water when it freezes?

Back

Water expands and becomes less dense when it freezes, which is why ice floats on liquid water.

Front

What is capillarity?

Back

The ability of water to flow in narrow spaces against gravity, due to cohesive and adhesive forces.

Front

Why is water called a versatile solvent?

Back

Water can dissolve many substances due to its polar nature, making it essential for biological processes.

Front

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

Back

It allows organisms to cool down through processes like sweating, as it takes a lot of energy to convert water from liquid to gas.

Front

How does water's density change with temperature?

Back

Water is most dense at 4°C; as it cools further to 0°C, it expands and becomes less dense.
