Base on the properties the substances possess the substance change phase from gas to liquid.

Explanation:

Generally, matter can exist in three phase namely liquid, solid and gas. The scientist has a container with a substance inside.

At first the substance moves away from each other. This means the substance was first in the gas phase. Gas molecules, because of the energy they possess, it can move rapidly and randomly and most at times move away from each other. The gas molecules tends to fill the whole volume of the container and the shape of gases are indefinite.

Later the molecules move around each other. This is a property of a liquid. A substance in liquid phase have the ability to move freely but they stay together because of the force of attraction holding them together. The substance only have the ability to move around each other because the forces holding them together won't allow them to move apart.
