Answer:
Rusting changes the chemical properties of iron making it weak and of less use so it is considered a non desirable change .
Solids have large intermolecular force and compact structure that's why they are rigid .
Yes air is matter because according to basic definition of matter , matter is anything occupying space and volume and we know that air occupies both so it's matter .
