Yes, all of them.
Any chemical difference exist.
Phase has nothing to do with chemical composition.
if the temperature of the substance is raised then the kinetic energy of the gaseous particles will also increase....
Yes it can, the only difference between liquid and gaseous water is it's physical form, not it's chemical composition.
when a substance exists as a liquid or solid under ordinary conditions its gaseous phase is called a vapor
An atmosphere implies the presence of a gaseous substance (such as air, in the earth's atmosphere, which is primarily made up of nitrogen and oxygen). Space is defined as the absence of atmosphere (as pure space consists of no solid, liquid or gaseous substance).
