These propertiesinclude color odor taste density melting point boiling point conductivity and hardness. Properties that can be determined without changing the composition of a substance are referred to as physical properties. Beside this how can physical properties be used to identify a substance.
A very common example is rotting of eggs that have a very different odor from fresh eggs. Where as chemical properties include the chemical reactionchanges at molecular level. A chemical change is a permanent change.
None of the above. This might be simply as matter of convenience. Versus a chemical property is something like flammability and digestion.
Intensive properties are used to identify a substance and do not depend upon the amount of substance density. Odor is generated when substances change composition. Physical properties are determined without changing the identity of the substance.
Common physical changes are melting resizing volume color density and crystal form. Do odors have properties. Common evidence of a chemical change includes a change in color smell temperature formation of a gas or a precipitate A physical change occurs when there is a change in the physical properties of a substance but not chemical compostation.
To a large extent it is believed that the shapes of molecules control how they smell. So lets kind of discuss really quickly what are some types of physical and chemical properties. Odor is generated when substances change composition.
This might be simply as matter of convenience. The law of conservation of mass states that the mass of all substances before a chemical change equals the mass of all the substances after the change. Physical properties include odortasteappearancemelting pointboiling point etc.
