Difference Between Physical And Chemical Change
The main dissimilarities or difference between physical change and chemical change can be pointed as follows:
1. Definition
Physical Change: It refers to the change in physical form or properties (size, shape, color etc.) of matter.
Chemical Change: It refers to the change in both physical and chemical properties of matter because of chemical reaction
2. State Of Matter
Physical Change: Not changed
Chemical Change: Changed
3. Change In Molecule
Physical Change: No change
Chemical Change: Changed
4. Reversible
Physical Change: Yes, it can be reversed
Chemical Change: No, it cannot be reversed
5. New Substance
Physical Change: New substance is not formed in physical reaction
Chemical Change: Completely new substance is formed in chemical reaction
6. Nature Of Change
Physical Change: Temporary
Chemical Change: Permanent
7. Production Of Energy
Physical Change: No
Chemical change: Yes
8. Energy Absorption
Physical Change: No
Chemical Change: Yes
9. Affect Of Change
Physical Change: Change in physical properties of matter such as size, color and shape
Chemical Change: Change in both physical and chemical properties of matter
10 Examples
Physical Change: Freezing of water, melting, cutting wood etc. are some of the examples of physical change
Chemical Change: Rusting of iron, burning a paper, mixing of acid and base etc. are some of the examples of chemical change
