Question
A plastic which can be softened on heating and hardened on cooling is called:a.Thermoplasticb.Thermoelasticc.Termite
Solution
The correct answer is a. Thermoplastic.
Thermoplastics are a type of plastic made from polymer resins that become liquid when heated. This characteristic allows them to be heated to their melting point, cooled, and reheated again without significant degradation. Hence, they can be softened on heating and hardened on cooling.

Plastics (will give) additional characteristics such as fire retardancy to allow them to be used in aircraft parts in the future. Injection-moulded parts (may include) glass or carbon fibres for strength. Plastics (can mould) with a foaming agent which (will reduce) the density and hence the weight of the final component and reduce the material required so reducing the cost. The list of plastics appears to be endless but they fall into two categories, thermoplastics and thermosets. Thermoplastics (can melt and recycle) into new parts. Thermoset plastics are stronger than thermoplastics but (cannot recycle) into new parts and have to be disposed of in other ways.
