What is air expansion apparatus?
is air expantion a chemical or physical change?
Is expansion physical or chemical change?
Expansion is a physical change because it involves a change in the state or size of matter without altering its chemical composition.
Is thermal expansion a chemical property?
No, thermal expansion is a physical property, not a chemical property. It refers to the tendency of matter to change in shape, area, and volume in response to a change in temperature. It does not involve any change in the chemical composition of the substance.
Is thermal expansion a chemical change?
No, thermal expansion is a physical change, not a chemical change. It occurs when a material expands or contracts in response to changes in temperature, without any change in the chemical composition of the material.
Is a firework cracking a physical or chemical change?
It is a chemical change as it releases gases into the air.
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.
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 metals with change in temperature a chemical change?
The expansion of a metal due to an increase in temperature is a physical change.This phenomenon is not a chemical change because the smallest unit of the material that possesses all of the chemical properties of the material is one atom, and no chemical changes to any of the atoms has occurred; none has been oxidized or reduced, nor has any other change in the chemical bonding of the metal atoms taken place.
When magnesium is burnt in the air is it a chemical change?
Yes. Magnesium burns in air brightly giving Magnesium oxide, witch is a chemical change.
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 inflation of a car tire a chemical change?
No. Nothing changes in its chemical nature.
Is a chemical change caused by whipping some cream?
No. What you are doing to the cream is introducing air to the material. Just like adding air to an automobile tire, the air does not produce a chemical change.
