It is not a chemical change because the steam can be changed back when cooling and nothing new has formed. :)
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.
a kettle when boiled is 1490 degees <3
When a kettle is boiling you are able to see the chemical reaction, from the stem leaving the kettle.
No, it is a physical change.
This is a chemical change.
The formation of steam from boiling water in a kettle is a physical change. It involves a phase change from liquid to gas without altering the chemical composition of the water molecules.
No, it is a physical change because the water is the same but just boiled
Boiling is a physical change.
When a tea kettle whistles, it is because the liquid inside turns to steam and is forced by pressure through the small opening in the kettle lid. This phase change is a physical change, not a chemical one.
Boiling water is a physical change, not a chemical change. The water molecules remain the same chemical composition (H2O) even though they change state from a liquid to a gas. This change is reversible.
Boiling water in a kettle is a physical change. This is because the change is reversible, and it involves a phase transition from liquid to gas without changing the chemical makeup of water molecules.
