Answer:
A physical property is an aspect of matter that can be observed or measured without changing its chemical composition. Examples of physical properties include molecular weight.
A chemical property may only be observed by changing the chemical identity of a substance. In other words, the only way to observe a chemical property is by performing a chemical reaction
Step-by-step explanation:
Properties of matter
The properties of matter are classified into; (I) Physical and, (ii) Chemical properties.
Physical properties: A physical property is an aspect of matter that can be observed or measured without changing its chemical composition. Examples of physical properties include molecular weight, density, color, melting and boiling point, etc.
Chemical properties: A chemical property may only be observed by changing the chemical identity of a substance. In other words, the only way to observe a chemical property is by performing a chemical reaction. This property measures the potential for undergoing a chemical change. Examples of chemical properties include and oxidation states, acidic or basic properties, flammability, heat of combustion, etc.
