Detailed explanation-2: -Physical: boiling and melting are physical changes. When water boils no bonds are broken or formed.

Detailed explanation-3: -Physical properties of matter include color, hardness, malleability, solubility, electrical conductivity, density, melting point, and boiling point.

Detailed explanation-4: -Some common examples of physical changes are: melting, freezing, condensing, breaking, crushing, cutting, and bending.
