List two characteristics of plastics
Answers
Answer:
plastic is not decomposed in soil.
it may be thick or thin...
hope it helped you....
Explanation:
Thermal conductivity: The thermal conductivity of plastics is low. That’s the reason why they meltdown when they are brought in contact with the heat.
Tensile strength: The tensile strength or the toughness of the plastics are dependent on the materials that are used in the production of the plastic. Usually, the tensile strength or the toughness of the plastics are less when compared to the alloys such as steel.
Lightweight: They weigh less than that of the metals which makes their transportation easy or carrying them from one place to another becomes easy.
Reactivity towards chemical: When plastics are compared with natural polymers such as cotton, wool, etc, plastics are not affected by the acids and alkalines
.Appearance: Usually plastics are transparent and can be coloured to desirable colours. Also, they can be moulded into shapes depending on their usages.
