Question

Give Reasons:-

(a) Plastics are used to store chemicals in laboratory.

(b) Handles of screw drivers are made of plastic.
​

Answer 1

Explanation:

a)Plastics are non-corrosive and non-reactive in nature. So they are used for storing chemicals in the laboratory. They are used for strong chemicals because they do not react with chemicals neither do they corrode.

b)Electrician's screwdrivers usually have plastic handles—because plastic insulates the user's hands from the risk of electric shock—as well as plastic tubing that runs much of the length of the shaft.
