Detailed explanation-1: -Physical properties are those characteristics that we can observe and measure without changing the composition of the substance. There are dozens of different physical properties, but odor, color, texture, and boiling point are some familiar ones.
Detailed explanation-2: -Examples of 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.
Detailed explanation-3: -Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
