the change is easily reversed so it is a physical change not a chemical 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.

When a kettle is boiled you can tell it is not chemical change?
There are 4 evidences of a chemical reaction : -Change of colour. -Formation of precipitate. -Release of energy. -Effervescence.
How is letting a copper kettle tarnish a chemical change?
Letting a copper kettle tarnish is a chemical change because it involves a reaction between the surface of the copper and elements in the air, like oxygen and sulfur compounds, forming new compounds like copper oxide or copper sulfide on the surface. This chemical reaction alters the composition of the copper material, leading to a permanent change in its appearance.
Is water boiling in a kettle a chemical or physical change?
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.
Is steam from a kedal a physica l or 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.
What happen in the boiling water on the kettle?
Materials can come in three phases, depending on physical conditions. They are gas, liquid, and solid. If you boil a kettle of water, you are first heating up the liquid water inside the kettle. But then at boiling temperature (which is about 100 deg C or 212 deg F) the liquid in the kettle starts to turn into gas, which we call steam. As a gas, that steam rises to the surface and that's when you start to see the bubbles we call boiling. So when we "boil a kettle" we are creating steam that creates the boiling bubbles.
When a kettle is boiled why is it not a chemical change?
It is not a chemical change because the steam can be changed back when cooling and nothing new has formed. :)

How many degrees does a kettle when boiled?
a kettle when boiled is 1490 degees <3
Is a kettle boiling a chemical reaction?
No, a kettle boiling is not a chemical reaction. It is a physical change where water is heated to its boiling point, causing the molecules to move faster and change from a liquid to a gas state.
A tea kettle begins to whistle chemical or physical?
The whistling noise of a tea kettle is a physical change. It is the result of the interaction between the steam escaping through the spout and the built-in whistle mechanism, causing vibrations that produce sound.

Which kettle would cool down faster a black shiny kettle or a shiny metallic kettle?
shiny because its cool when after boiled also the black wouldnt cool as it attracts heat.
Is water boiling in a kettle a chemical or physical change?
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.
Is boiling a kettle a chemical change?
Boiling a kettle is a physical change because it is a change in state from liquid to gas without altering the chemical composition of the water. The water molecules are simply being heated to a point where they gain enough energy to overcome the intermolecular forces holding them together, turning into steam.
Is steam from a kedal a physica l or 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.
When a tea kettle begins to whistle is this a physical or chemical change?
No. the hissing and steaming is simply the Physical Change of water boiling, and the steam causes an increase in pressure thus the whistle. During a Physical Change, some properties of material change, but the composition of the material does not change.
What happens to kettle when water boiled?
Hi there when the kettle is boiled the water inside is heated up to boiling point.This is because the coil inside the kettle gets heated by electricity very rapidly and transfers the heat to the water making it boil. The coil some times get a build up of natural chemicals on it such as limescale and therefore has to be cleaned . Now a days we have filter kettles which get rid of the limescale as water is added to the kettle.
