Melting ice is considered a physical change because it involves a change in the state of matter, from solid to liquid, without any change in the chemical composition of the substance. The molecules in ice remain the same and do not undergo any chemical reactions during the melting process.
On the other hand, the creation of the compound water (H2O) involves a chemical change. Water is formed through a chemical reaction known as hydrogen bonding, where two hydrogen atoms bond with one oxygen atom. This reaction involves the breaking and forming of chemical bonds between atoms to create a new substance with different chemical properties.
In summary, melting ice is a physical change because it only involves a change in the physical state, while creating water (H2O) is a chemical change because it involves the formation of a new compound through a chemical reaction.
Melting ice is a physical change while creating the compound, water (H2O), is chemical. Why?
