Question

plastic articles available in all possible shapes and sizes. can you tell why?

Answer 1

Plastic is a unique material which becomes soft on heating and hard on cooling. It melts at moderately high temperature without decomposing. As liquida have tendency to take the shape of container,therefore, when, molten plastic is poured into different vessels,it takes the shape of vessels on cooling. Thus,a plastic can be moulded into different shapes and sizes.Hope it helps.
