Answer:
Changes that can be reversed are Physical Changes:
- Change in shape (Clay)
- Change in size (Rubber Band)
- Change in state (Ice to water and vice versa)
Changes that can not be reversed are of two types:
- Irreversible physical change
- Chemical change
1. Irreversible physical change
- Tearing of paper (Paper remains paper but we cannot bring back the initial full sheet back)
2.Chemical change
- Burning of paper (Paper is lost and we have an entirely new product)
