Detailed explanation-1: -During boiling, water changes from liquid to gaseous state. Hence it is a kind of physical change.
Detailed explanation-2: -When water is boiled, it undergoes a physical change, not a chemical change. The molecules of water don’t break apart into hydrogen and oxygen. Instead, the bonds between molecules of water break, allowing them to change physically from a liquid to a gas.
Detailed explanation-3: -Research shows that students frequently use the term chemical change to describe changes in physical state. Freezing and boiling are considered to be examples of chemical reactions.
Detailed explanation-4: -Water boils at 100 ° C and at this point, there will be a change of state from liquid gas. The volume occupied by the matters can change and no new substance is formed.
