Properties of Water

Front

What is the specific heat of water?

Back

Water has an unusually high specific heat, meaning a large amount of heat is required to raise its temperature.

Front

What is the chemical formula for water?

Back

The chemical formula for water is H2O.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What causes water to move from the roots to the leaves of plants?

Back

Capillary action pulls the water molecules up like a chain.

Front

What is a polar molecule?

Back

A polar molecule is one that has an opposite electrical charge on each end.

Front

Why does ice float in liquid water?

Back

Ice floats in liquid water because it is less dense than liquid water.

Front

What is cohesion in water?

Back

Cohesion is the attraction between water molecules, which allows them to stick together.

Front

What is adhesion in water?

Back

Adhesion is the attraction between water molecules and other substances.

Front

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

Back

Water's high heat of vaporization allows it to absorb a lot of heat before it evaporates, helping to regulate temperature.

Front

What is surface tension in water?

Back

Surface tension is the cohesive force at the surface of water that allows it to resist external force.
