What is Physical changes
A physical change is a change to the physical as opposed to chemical properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.
An extensive property is a property that varies with the amount. Depending on the amount of matter, the ratio of 2 extensive properties is intensive.
An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example, the temperature of a system in thermal equilibrium is the same as the temperature of any part of it.
3 phase changes of solid-, liquid and gas are intensive as their identity won't change unless there is a chemical change
