Answer: Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color, odor, taste, density, melting point, boiling point, conductivity, and hardness.
Explaination:
By using Physical properties unknown substance can be identified as it involves determination of a substance with out changing their composition or property include color, odor, taste, density, melting point etc.
What are the difference between physical and chemical property ?
Chemical properties can be observed or measured when a substance undergoes any type of changes chemically while Physical properties can be observed without changing anything.
In chemical property, chemical reaction is conducted to show the property of the substance while in physical property No chemical reaction occur.
Chemical properties related to chemical bonds while Physical properties do not have such a relationship.
Chemical properties include radioactivity, toxicity, flammability, heat of combustion, etc. while physical properties include Molecular weight, boiling point, melting point, freezing point, volume, mass, length, density shape, solubility, etc.
