Yes, boiling water is considered a chemical change. When water reaches its boiling point and turns to steam, the molecules have gained enough energy to break their bonds with each other, forming new compounds. This process is called hydrolysis.
The end result is that the water molecules are now less stable than they were before.
When water is heated and reaches its boiling point, the physical properties of the water change. The water molecules gain energy and move faster, which causes the water to boil. However, the chemical composition of the water does not change.
Therefore, boiling water is a physical change, not a chemical change.

Is Boiling Water a Chemical Change Or Physical Change?
When water is heated, it undergoes a physical change. This is because the molecules of water are gaining energy and moving faster, but they are not changing into new molecules. When water boils, the molecules have gained so much energy that they turn into gas molecules (water vapor).
This process is called evaporation.
Why is Boiling Water a Chemical Change?
Water boils when it reaches its boiling point, which is 212 degrees Fahrenheit (100 degrees Celsius) at sea level. When water reaches this temperature, it changes from a liquid to a gas.
Boiling water is a physical change because the molecules of water are simply changing states from liquid to gas.
However, some people consider boiling water to be a chemical change because when water reaches its boiling point, it undergoes a chemical reaction called hydrolysis. Hydrolysis is when the molecules of water break down into hydrogen and oxygen gases.
Is Boiling Water a Chemical?
When water is heated, the molecules gain energy and start to move faster. As they move faster, they bump into each other more often. Eventually, the molecules have so much energy that they break apart from each other entirely, forming a new substance: steam.
The process of breaking apart water molecules into steam is called boiling. It requires a lot of energy to do this – so much energy, in fact, that it’s considered a chemical reaction. In other words, yes – boiling water is a chemical reaction.
Is Boiling Something a Chemical Change?
When you boil something, it is a physical change. The boiling point of water is 100 degrees Celsius (212 Fahrenheit). When you heat water to this temperature, the molecules begin to move faster and the water turns into steam.
However, if you were to add something to the water before boiling it, such as a piece of fruit, this would create a chemical change. The heat from the boiling water would cause a chemical reaction in the fruit, changing its structure and taste.
Is boiling water a physical or chemical change?
Is Dissolving Sugar in Water a Chemical Change
When you add sugar to water, the sugar molecules begin to interact with the water molecules. This interaction causes the sugar molecules to break apart and spread throughout the water. Over time, the sugar will continue to interact with the water molecules and eventually dissolve completely.
The process of dissolving sugar in water is a chemical change because it involves a chemical reaction between the sugar and water molecules. When the sugar breaks apart and spreads throughout the water, it forms new bonds with the water molecules. This change is irreversible, meaning that once the sugar has dissolved in water, you cannot get it back out again.
Conclusion
Yes, boiling water is considered a chemical change. When water reaches its boiling point and turns to steam, the molecules have gained enough energy to break apart and form new bonds. This makes steam different from liquid water, even though they are both made up of H2O molecules.
