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 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 making chalk dust a chemical change?
No, it is a physical, not chemical 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.
Is a nebula a physical change or a chemical change?
A nebula is a physical change. It is a cloud of gas and dust in space that is not undergoing any chemical reactions. The process of a nebula forming into a star involves physical changes such as gravity causing the gas to condense and heat up.

Is atmosphere being a gas physical or chemical change?
No, 'atmosphere' is NOT a change at all! It is a mixture of gasses and dust, mist or rain.
Is a nebula a physical change or a chemical change?
A nebula is a physical change. It is a cloud of gas and dust in space that is not undergoing any chemical reactions. The process of a nebula forming into a star involves physical changes such as gravity causing the gas to condense and heat up.
Is splitting wood chemical or physical change?
Flammability is an example of physical and chemical properties.
Is pulverized chalk a physical or chemical change?
Grinding chalk to chalk dust is a physical change because the texture and size may change but the its molecules are still the same.An example of chemical change is burning paper because ash is chemically different from paper.
Which of the following is an example of a physical rather than a chemical change saw dust that is piling up under a table saw or a cigarette being smoked?
Saw dust
Is wood sawed and made into a toy box a chemical or physical change?
Physical-it is still wood, just in small pieces
Is tarnishing of metal a physical or chemical change?
Tarnishing of metal is a chemical change because it involves a reaction between the metal and substances in the environment (such as oxygen or sulfur compounds) that forms a new compound on the surface of the metal, altering its properties.
Is coal dust chemical or a physical toxicant?
Coal dust is considered a physical toxicant because it can cause harm through its physical properties, such as being inhaled and causing respiratory issues or skin irritation. Chemical toxicants, on the other hand, refer to substances that cause harm due to their chemical properties or composition.
