Image of a level with an air bubble in the middle of a horizontal tube.

• The air bubble is at the center indicating the surface is level.

• The air bubble is at the left end indicating the surface is inclined to the right.

• The air bubble is at the right end indicating the surface is inclined to the left.

• The air bubble is moving rapidly indicating the surface is unstable.

How can materials be classified based on their shape and volume?
