When a kettle is boiling you are able to see the chemical reaction, from the stem leaving the kettle.
No.
That would be the boiling point of water, or somewhere below if the kettle is faulty. The boiling point of water is 100 degrees Celsius.That would be 212 degrees Fahrenheit.
I was thinking of boiling water, but that's physical
No. There is a phase change as the water is converted into steam, but no chemical reaction occurs. A chemical reaction is when elements or molecules recombine to form other substances. For example, mixing hydrochloric acid with magnesium produces magnesium chloride, and hydrogen gas is given off. Another chemical reaction is the simple oxidation (rusting) of iron, which forms iron oxide.
A chemical reaction
No.
No, boiling is not always a sign of a chemical reaction.
Its a chemical reaction :]
During boiling the chemical composition is not changed.
chemical
no, boiling is a physical change
Water boiling is a physical change and not a chemical reaction. In a physical reaction there is no new substance formed as is the case with chemical reactions. In boiling water there is no new substance produced.
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.
Boiling water out of a kettle can be used for boiling noodles for soup or spaghetti.
If you're referring to the residue left in the kettle after the boiling of water. It is known as calcium carbonate. The chemical equation is CaCO3. Hopes This Helps
a physical becauseb it does not effect the chemical make up
Freezing and boiling do not change the chemistry in the process.
