Ice melting is a physical change because the composition of molecules remains the same, representing a change in physical properties. The transformation from ice to water demonstrates a reversible process without altering the chemical composition.
Ice melting is a physical change because even though the ice transforms into water, the composition of the molecules remains the same. The atoms in ice, which are hydrogen and oxygen, do not change into different atoms during the melting process.
During a physical change like melting, the particles rearrange themselves without breaking up, demonstrating a change in physical properties but not the chemical composition. For example, when ice melts, water molecules move apart without altering their elemental makeup.
This transformation from ice to water is reversible, unlike a chemical change where new substances are formed. Therefore, melting ice represents a physical change as the identity of the substance remains constant.
