Question

As we know that the leaves of plants are waterproof due to cuticle.On thesame way, take some pieces of paper of leafsize and make them waterproof. After completion, put half of these paper pieces in cold water and half in hot water. Do all the pieces of paper remains waterproof? Explain your observations and results withjustifications.

Answer 1

The paper pieces may not remain waterproof in hot water, but they may remain waterproof in cold water.

Step-by-step explanation:

Plants have a waxy cuticle on their leaves that makes them waterproof. This cuticle helps to reduce water loss through transpiration. If you take pieces of paper the size of leaves and make them waterproof using a wax coating, they will also become waterproof.

However, when you put half of the waterproofed paper pieces in cold water and half in hot water, they may not remain completely waterproof. The wax coating may start to melt or become less effective in hot water, allowing water to penetrate the paper. In cold water, the wax coating may not be significantly affected, so the paper pieces may still remain waterproof.

Therefore, the observation and result of the experiment would be that the paper pieces may not remain waterproof in hot water, but they may remain waterproof in cold water.
