Question

Tearing of paper is said to be a change that cannot be reversed. What about paper recycling?​

Answer 1

When we tear a paper the shape and size of the paper changes. Hence, tearing of paper cannot be reserved.​

Recycling of paper:​

the quality, colour and texture of the paper changes on recycling​

• we get a different type of paper not the original one.​
• Therefore, recycling of paper is an irreversible change​

Hence, both recycling paper and tearing paper are irreversible.​
