Chemical Changes

 

 physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. There are many more examples. Note that measuring each of these properties will not alter the basic nature of the substance

physical properties of an element are properties you can feels, touch, see. Such as its state,color, size, density.
For example, an ice cube has a solid state.
Water has a liquid state, and air has a gas state.
