Question

(a) Give reason for the following:
(i) Plastic containers are of various sizes.
(ii) Plastics are used to store chemicals.
(iii) Handles of frying pans are made of plastic.​

Answer 1

Explanation:

i)Since liquid has the tendency to take the shape of the container, the molten plastic is poured into different vessels. And thus can be made into any shape and size making it easy to create articles.

ii) Plastic bottles are commonly used to store chemicals in a chemical laboratory because plastics are non-reactive. They are inert to air and water. They are non-corrosive, therefore we can store chemicals in them safely.

iii) Plastic is a insulator. So when the frying pan is used for cooking something, it gets heated up. So in order to enable handling of the frying pan at this time, the handles are made of plastic which does not conduct electricity, and therefore does not heat up.
