Physical changes are those that can be observed.
Volume is a physical property.
If you burn something it is a chemical change, however if you melt of boil it, it is a physical change.
lighting is a chemical change
Chemical change
The way I remember the difference, is: a physical property is a property that you can observe without changing it (or observe without a chemical reaction). So properties like melting point, boiling point, density, color, hardness are all physical properties. A property like 'reacts with water' could only be observed by performing the reaction to observe the change.
physical (because you can observe it without inducing a chemical reaction).
they are harder to observe because youcan't be seen.
When you can observe something's characteristics, they are called physical traits. These are the things you can see, hear, smell.

Physical--- melting something doesn't change its chemical composition.
