plastic are: (a) good conductor of heat (b) good conductor of electricity (c) mouldable and strong (d) corrosive
Answers
Answer:
) Plastics are poor conductors of heat and electricity. ... They are non-corrosive and therefore plastic bottles are used in chemical laboratories to store chemicals. 4) Plastics easily melt on heating and therefore they can be moulded into different shapes.
Answer:
The four properties of plastics are:
1) Plastics are poor conductors of heat and electricity. That is why they are used to make handles of cooking utensils and electrical wires. Cords of electrical appliances and cables also have plastic coating.
2) Plastics are insoluble in water and that is why we use plastic buckets to store water and use plastic glasses to drink water.
3) Plastics are inert to air and water. They are non-corrosive and therefore plastic bottles are used in chemical laboratories to store chemicals.
4) Plastics easily melt on heating and therefore they can be moulded into different shapes. Hence, they are used to make things such as toys, buckets etc.
