That is a physical change - at least the pump is (air in, air out, with no chemical change). The energy required to run the pump probably will come from a chemical reaction though: an electric generator burning fuel to run the generator or food being digested and converted to energy in the muscles if it is a person powering it

Is a firework cracking a physical or chemical change?
It is a chemical change as it releases gases into the air.

Is humidifiers putting moisture into the air a physical or chemical change?
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.

Is boiling water evaporating into the air a physical or chemical change?
Boiling and evaporation are physical changes.
If before a basketball game the ref uses an air pump to inflate the basketball is it a chemical or physical change?
Inflating a basketball with an air pump is a physical change because it does not involve any change in the chemical composition of the materials involved. The air is simply being forced into the ball, causing it to expand and increase in volume, but the fundamental chemical makeup of the ball remains the same.
Is filtering air to remove dust and pollen a physical or chemical change?
Filtering air to remove dust and pollen is a physical change because the process does not alter the chemical composition of the dust and pollen particles. It simply separates them from the air through physical means, such as using a filter.
Is a firework cracking a physical or chemical change?
It is a chemical change as it releases gases into the air.
Is Water vapor in the air an example of a physical or chemical change?

Is dust settling out of the air a chemical change?
No, dust settling out of the air is a physical change, not a chemical change. It is a result of gravity causing the dust particles to fall out of suspension in the air without any chemical reactions occurring.
Is expansion of air chemical change?
No. "Chemical change" means that the bonds between atoms are rearranged.
Is reacts with air a chemical or physical change?
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.

What is air expansion apparatus?
is air expantion a chemical or physical change?
Are filtering air to remove dust and pollen a physical and chemical change?
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.
