Answer:
Example of temporary changes :
1) Freezing of water :
When we decrease the temperature of normal liquid water to 0°C ,the water becomes solid ice.
But this change is temporary, because with the help of little amount of heat we can again change the ice into liquid water.
2) Electromagnet : When we pass electricity in an electromagnet the magnetism of that electromagnet works perfectly.
But when we cut the electricity flow in an electromagnet the magnetism vanishes.
Here,the magnetism is a temporary change.
Permanent changes :
1) Combustion : When we burn any substance we cannot get the substance back which it was before the combustion.
2) Chemical reaction : There are many types of chemical reactions which are totally irreversible and are permanent changes.
