No. It's an observed fact, not a "change" of any sort, chemical or otherwise.
physical
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
The state of matter is a physical property at any temperature.
At room temperature californium is a solid metal.
Baking soda is a solid at room temperature.
physical property because the chemical makeup of the ice remains the same
The physical state of C6H10 in a chemical equation would depend on the specific context. Generally, C6H10 is a liquid at room temperature and pressure, however in a chemical reaction it could be in a different state based on the reaction conditions.
Vanadium is a solid metal at room temperature.
Ethane is a colorless, odorless gas at room temperature and standard pressure. It is a hydrocarbon with the chemical formula C2H6.
Pure Magnesium (Mg) is Solid at room temperature
No metals are in a gaseous form at room temperature. Most are solids and one (Mercury chemical symbol Hg) is a liquid.
it indicates the physical state at room temperature
