Dear Student,

​​​​​​The Differences between physical and chemical changes are:
 

Physical Change	Chemical Change
1. A physical change is a change of state of matter in which no chemical reaction is involved.	1. A chemical change involves a chemical reaction to take place.
2. Here no new substance is formed except state change.	2. Here new substances are formed.
3. Physical change is a reversible change	3. Chemical change is an irreversible change
eg: Melting of wax of a candle is a physical change as the molten wax can solidify back.	eg: The buning of flame of a candle gives out new substances which cannot be brought back to their original form.Thus it is a chemical change.
