[@mitaleesharma7489]

Mam whether crystallization is physical change

[@user-exploretheworld]

yup it is😃

[@vijaychandwani5823]

Please tell , when a glass breaks we can melt it and reverse it again
Same with paper it can be recycled again. So it should be a reversible physical change.
This was taught in our class.please tell✨

[@vineetamendiratta5121]

No, this is not reversible
Recycling cannot create a perfect new product. The quality will be lower
I hope I wasn't late to answer
