Steam is a gaseous phase of water. It is also "physically" invisible.
If the steam is being produced by boiling water the physical property is gas and the chemical properties are H2O.
Two physical properties that can vary without changing the substance are temperature and pressure. For example, water can exist as a solid (ice), liquid, or gas (steam) at different temperatures and pressures, but it remains chemically the same H2O molecule.
