Is liquefying of air a physical change or chemical change?
Please note that a "change of state" involves TWO states, not just one. Using just the three most common states of matter: * A solid can change to a gas * A liquid can change to a gas * A gas can change to a liquid * A gas can change to a solid * A solid can change to a liquid * A liquid can change to a solid The first four changes in the list above involve gases.
Is reacts with air a chemical or physical change?
It is a chemical change.
Is heating the air in a balloon a chemical change or a physical change?
Physical.
How can you get nitrogen out of the air?
by fractional liquefaction, you separate various gasses from air by the temperature they liquify.
Is filtering air to remove dust and pollen a physical or chemical change?
It’s a physical change 😑
What are the applications based on change of physical state of matter by pressure?
The most important is the liquefaction of gases.
When oxygen is liquefied is it a physical or chemical change?
Physical because it is still Oxygen. A chemical change results in a chemical equation and thus a new substance. No new substance = no chemical change. Liquefaction is a physical property.

What are physical change and chemical properties of matter?
Physical changes: vaporization, melting, sublimation, liquefaction etc. Chemical changes: oxydation, combustion, polymerization, radiolysis.
Is liquification of air a physical change?
Yes, liquification of air is a physical change.
What is the difference between liquefaction and condensation?
liquefaction-change from solid to liquid state condensation-change from gas to liquid-just opposite of evaporation
Is reacts with air a chemical or physical change?
It is a chemical change.
What is the change from liguid to solid called?
Liquefaction
What state changes when you cook something on the stove?
Cooking is a chemical change; but some physical changes may be involved: de freezing, liquefaction, evaporation.
Is heating the air in a balloon a chemical change or a physical change?
Physical.
What is difference between condensation and liquefaction?
Liquefaction is a change to a liquid from either a solid or a gas; whereas condensation is a change only from gas to liquid. Liquefaction takes place at very low temperatures(eg-Air is liquefied at -200degrees c) whereas condensation does not need such low temperatures, it occurs when water vapor changes to droplets of water on a glass of water taken out of a fridge.
Is Water vapor in the air an example of a physical or chemical change?
Physical change
