Physical and chemical changes:
Difference between physical and chemical change are several and it is important to understand them to be able to understand these topics better. The comparisons and differences between physical change and chemical change are given below along with their examples.
The properties that can be observed and specified like colour, hardness, rigidity, fluidity, density, melting point, boiling point etc. are the physical properties. The interconversion of states is a physical change because these changes occur without a change in composition and no change in the chemical nature of the substance.
To understand the physical and chemical properties and changes better, it is important to know what they are and their characteristics.
Burning is a chemical change. During this process one substance reacts with another to undergo a change in chemical composition. Chemical change brings change in the chemical properties of matter and we get new substances. A chemical change is also called a chemical reaction.
