as we know that the leaves of plants are waterproof due to cuticle. on the same way, take some pieces of paper of leaf size and make them waterproof. after completion, put half of these paper paper pieces in cold water and half in hot water. do all the pieces of paper remains waterproof? explain your observations and result with justification?

No

Explanation:

Cuticle are a layer of wax that covers the plant leaves of all species. It is wax covering and is produce by he leaves to cover its surface. This wax covering helps to reduce the transpiration of leaves, i.e. the loss of water from its surface. It makes the leaves waterproof.

According to the question, if we make some paper pieces water proof by applying wax on it and put half pieces paper in to cold water and remaining half in to the hot water, we see that wax paper pieces that are put into hot water melts and the paper pieces get wet. It no longer remains water proof.
