Q.1 what do you mean by chemical changes and physical changes.explanation with suitable example?

Chemical changes

            A chemical changes is a type of changes it is a form of matter   new substance are formed after under goes chemical reaction and having it's identity .It can not reverse some time later is known as chemical changes.

Example  of chemical changes
1.Burning of wood
2.Digesting food
3.Reaction with acid and base
4.souring of milk
5.Rusting of Iron
6. Burning of candle

Physical changes

             A physical changes is a type of change  which is a form of matter ,No new substances are formed and substances is not transformed into another.The size or shape of matter  may be changed but no chemical changes occur.physical changes are reversible but chemical changes are irreversible.

Example of physical changes
1. melting of wax
2.freezing of water in ice
3.Boiling water
4.Evaporarion of alcohol
5.Breaking a bottle
6.shredding paper

   Important key points

• 1.A chemical change results from a chemical reaction, while physical changes not from reaction.
• 2.Examples of chemical changes are burning,  rusting and rotting.
• 3.Examples of physical changes are melting,boiling, , freezing, and shredding.
• 4.it is reversible changes,when energy given input .

Conclusion

        In chemistry ,physical and chemical changes found in chemistry ,it is form of matter , physical changes is reversible and chemical changes is irreversible.
I hope it will helpful for you and chemical and physical changes are always all around  science keep in mind and make  your passion and study well always.And simple way to find what is chemical and physical changes for this you have to do experiment and judge a substance it is chemical or physical write it down in your notebook and learn it .
