It is a chemical property as air sensitive compounds react with oxygen or air to yield a different compound. Physical properties don't alter the composition of the compound but rather the behaviour through different molecular arrangement.
Gasoline has various chemical properties (particularly, it burns very well) and its combustion products have other chemical properties (they don't burn as well) but it would not be correct to say that gasoline in any sense BECOMES a chemical property. Chemicals have properties, they don't become properties.
No. This is because it is demonstrating the fact that it is less dense than the air. Density is a physical property. Therefore the helium balloon rising to the ceiling is not a chemical property, and instead a physical property.
If something is liquid, that's its physical state. Solid, liquid, and gas are the states of matter as they began in the modern era. This differentiates matter from the time when things were earth, air, fire or water, or a combination of them. Note also that we've added plasma and a couple of other physical properties to solids, liquids and gases.
Physical
The humidifier putting moisture into the air is a physical change. It involves adding water vapor, which is a change in the physical state of water from liquid to gas, without altering the chemical composition of the water molecule.
When a substance reacts with air, it typically undergoes a chemical change. This is because the interaction with air usually involves a chemical reaction where new substances are formed with different properties than the original substance.
Filtering air to remove dust and pollen is a physical change. This is because the process does not alter the chemical composition of the air or the dust/pollen particles. Instead, it simply separates the particles based on their physical properties.

Iron: Chemical properties - Forms oxides when oxidized. Physical properties - Silver-gray color, good conductor of electricity, magnetic. Uses - Used in construction, manufacturing, and transportation. Copper: Chemical properties - Forms greenish patina when exposed to air. Physical properties - Reddish-brown color, good conductor of electricity and heat. Uses - Used in electrical wiring, plumbing, and electronics. Aluminum: Chemical properties - Forms a protective oxide layer when exposed to air. Physical properties - Lightweight, silver-white color, good conductor of heat. Uses - Used in aerospace industry, transportation, and packaging.

The formation of rust from iron and oxygen is a chemical reaction. This is because the iron reacts with oxygen in the air to form a new compound, iron oxide (rust), which has different chemical properties from the original iron.
Earth's physical properties are:Water,Dust,Rock,Air,and Iron
Burning Mg in air is a chemical change. When magnesium reacts with oxygen in the air, it forms magnesium oxide. This is a chemical reaction that results in the formation of a new substance with different properties than the original magnesium.
Chemical
No, inflating a bike tire is a physical change because it does not change the chemical composition of the tire or the air being pumped into it. When air is added to the tire, it simply increases in volume and pressure without altering its chemical properties.
