No, it is a physical change because the water is the same but just boiled
No, it's a physical change. A chemical change is when one substance changes into another substance. This is only a change of state, so it's physical.
No, boiling (the process of .. ) is physical (liquid water to steam or vapor).
However boiled water is the same compound as unboiled, so UNchanged.
No, it is a physical change.
the change is easily reversed so it is a physical change not a chemical change
Yes, because you can cool the water back and it would be normal water again
There are 4 evidences of a chemical reaction : -Change of colour. -Formation of precipitate. -Release of energy. -Effervescence.
In short, NO.If nothing is added to the water, the temperature will not change. And as long as the air pressure doesn't change, the temperature of the boiling water will not either.

Boiling is a physical change.
Boiling is a physical phenomenon, a change of phase.
It is a physical change because the water only changes its state from liquid to gas.
Water boiled to make pasta is a physical change because it is changing its state of matter. It is changing from a liquid to a gas.
This is a chemical change.
the change is easily reversed so it is a physical change not a chemical change
The chemical changes are in the campfire- the wood combines with oxygen from the air, releases heat and carbon dioxide. The water does not have a chemical change, but does have a physical change- it changes from a liquid (water) to a gas (steam).
This is a physical change. You can separate the salt and water by the physical process of distillation or evaporation where the water is boiled away and the salt is left behind.
It is not a chemical change because the steam can be changed back when cooling and nothing new has formed. :)
