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 is the charge of the oxygen atom in a water molecule?

Back

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

Front

What does it mean for a water molecule to be polar?

Back

A polar molecule has opposite charges on opposite ends, meaning one end is slightly positive and the other is slightly negative.

Front

Why does ice float on water?

Back

Ice floats because water expands when it freezes, making ice less dense than liquid water.

Front

What causes surface tension in water?

Back

Surface tension in water is caused by hydrogen bonds between water molecules, leading to cohesion.

Front

What is the molecular formula for water?

Back

The molecular formula for water is H2O, indicating it has two hydrogen atoms and one oxygen atom.

Front

How do hydrogen bonds affect water's properties?

Back

Hydrogen bonds give water its unique properties, such as high surface tension, high specific heat, and the ability to dissolve many substances.

Front

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

Back

Water's high specific heat allows it to absorb and retain heat, helping to regulate temperature in the environment.

Front

What is adhesion in water?

Back

Adhesion is the property of water that allows it to stick to other substances, such as glass.

Front

How does water's density change when it freezes?

Back

Water's density decreases when it freezes, which is why ice floats on liquid water.
