Answer 2

Explanation:

Hello friend,

Good question !

Required Answer:-

➔ How is chemical change different from physical change ?

↪First, let's know what is definition of both of them:-

Physical change is a change in which the matter,properties,proportion,volume,etc of the thing undergoing physical change doesn't change. The appearance of the substance may change but the change is fully reversible and it doesn't change the volume,properties,etc of the matter.

For example:-

• Melting of ice

• Boiling water

• Crushing a can

Chemical change is an irrreversible change in which the substance change by it's properties,proportion,volume,etc which can't be reversed back to it's previous state.

For example:-

• Burning of sugar

• Cooking food

• Making curd

The main and only difference between chemical and physical change is that in physical change the matter can return to it's previous state but in chemical change the matter can't be reversed to it's previous state because the burning/reaction have changed the material completely but in physical change it is just giving the substance another form which can be reversed again and again.

hope it helps you....
