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 chlorine gas liquefies at - 35 degree celsius under normal pressure a chemical or a physical change?
The liquefaction of chlorine gas at -35 degrees Celsius under normal pressure is a physical change. This is because the change in state from a gas to a liquid does not alter the chemical composition of the substance, only its physical state.
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 heating the air in a balloon a chemical change or a physical change?
Heating the air in a balloon is a physical change because it does not involve any chemical reactions. The heat causes the air molecules to move faster, increasing their kinetic energy and causing the balloon to expand.
Is a tire inflated with air a physical or chemical change?
physical change. the rubber is still rubber and the air is still air, so NO chemical change has occured
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
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 Water vapor in the air an example of a physical or chemical change?
Physical 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.
What is the word for separating air?
Air components are separated by criogenic distillation.
