No, it is a physical change because the water is the same but just boiled
No, it is a physical change.
When a kettle is boiled, it is not a chemical change because the water molecules are simply changing state from liquid to gas due to the heat, without any change in their chemical composition. The process is reversible, as the water vapor can condense back into liquid water.
There are 4 evidences of a chemical reaction : -Change of colour. -Formation of precipitate. -Release of energy. -Effervescence.
Boiling water to make tea is a reversible physical change. When water boils, it changes from liquid to gas, but it can easily be reversed by cooling the gas back into liquid form. No new substances are formed during this process, indicating that it is a physical change, not a chemical reaction.
No, this is definitely a physical change, absolutely not a chemical.

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.
This is a chemical change.
Boiling water to make pasta is a physical change because the water undergoes a phase change from liquid to gas, but its chemical composition remains the same. The molecules in water are rearranged, but no new substances are formed during the boiling process.
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).
The bubbling of water when boiled is not the result of a chemical reaction. It is due to the conversion of liquid water to water vapor, which forms bubbles as it rises to the surface. This process is physical in nature, involving the phase change from liquid to gas.
It is not a chemical change because the steam can be changed back when cooling and nothing new has formed. :)
Water changes from a liquid phase to a gaseous phase when it is boiled.
