Water Properties

Front

What is cohesion in water?

Back

Cohesion is the property of water that allows it to stick to itself, resulting in surface tension.

Front

What causes water's cohesion?

Back

Water's cohesion is caused by hydrogen bonds between water molecules.

Front

What is surface tension?

Back

Surface tension is the elastic tendency of a fluid surface that makes it acquire the least surface area possible, allowing objects to float on it.

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

What is the chemical formula for water?

Back

The chemical formula for water is H₂O.

Front

Why does ice float on water?

Back

Ice floats on water because it is less dense than liquid water due to the expansion of water molecules when they freeze.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of a substance by one degree Celsius.

Front

Why is water known as the universal solvent?

Back

Water is known as the universal solvent because it can dissolve more substances than any other liquid.

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

What role do hydrogen bonds play in water's properties?

Back

Hydrogen bonds are responsible for water's unique properties, including cohesion, adhesion, and high specific heat.
