Well, if you were for example discussing the the physical change of substance from one state to another, eg. Ice to liquid water than the relation to physics concerns energy. When discussing temperature change what you are in reality dealing with is how much energy a given substance or object contains.
a physical change is a change in any physical property of a substance, not in the substance itself
a physical change is a change in any physical property of a substance, not in the substance itself
The answer to, ' when repeating chemical and physical properties of elements change periodically with the elements' atomic numbers it is called the?'Periodic law, is the answer. PERIODIC LAW !orPeriodicity of the chemical elements properties.

It is chemical. It is chemical because when salt is formed from elements it becomes a chemical and not a physical.
It is a physical change when water boils. See also related answers.
A physical property can be observed without changing what the substance is made of. A chemical property can only be observed by altering a substance through a chemical change.
Yes, it is a chemical change; new compounds (elements) are formed !
Crushing creates a physical change in the size of the pieces but it does not change their chemical make up.
Chemical inertness means no or very less ability to react with other elements or compounds , it depends mainly on the valency of elements. elements usually react with other substances because they have to satisfy their valency by filling their octets , but those elements which already have a completely filled octet shows no or very less reactivity towards other elements. and rarely react with other elements . this is known as chemical inertness.
