The best way to know when a physical change is taking place is to observe. There will be a visible change in physical changes.
The physical change in a substance directly between gas and solid without becoming a liquid.
When gases are cooled, they convert to liquids. This is termed as condensation.
This would be defined as a physical change. In chemistry, this would be defined as anything from a change in mass or volume to a change in state (solid, liquid, gas). As long as the substance does not change in molecular structure, it is mostly a physical change. Common indicators of a chemical change is change in color, production of light, production of extensive heat, production of uncommon smells, or even bubbling.
The change from liquid to gas at the surface of a liquid is known as vaporization.
The repitation of physical and chemical properties of elements periodically is called periodicity
