No, not always. But mostly.
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
physical, because it can be easily reversed
It depends. Physical can be easily reversed. Chemical is hard, if not impossible to reverse.
Change of state from a liquid to a solid and back again.
A physical change is a change that can be reversed easily and no new substances are made. Examples are state changes ie. solid to liquid or liquid to gas.
An example of a physical change that can be reversed is melting ice into water; this can be reversed by freezing the water back into ice. An example of a physical change that cannot be reversed is breaking a glass; once the glass is shattered, it cannot be returned to its original form.
Yes, because it can be reversed by condensation. Physical change = Reversible Chemical change = Irreversible

Cooking an egg is a chemical change because it cannot be reversed.
physical change.the condition can be reversed by changing the temperature & it is only a temporary change.
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.
No, it's a chemical change. A physical change is one which can be reversed. Like ice to water to ice etc.
A physical change. It can be reversed.
