What are the differences between thermoplastics and thermosetting plastics? give examples and draw a simple diagram to show what kind of linkages are there in the polymer chains.

on the basis of the reaction of heat in plastic , their are two types of plastics :

Thermoplastics : Plastics which easily get deformed (become soft )on heating and also get bend easily are known as thermoplastics .

examples :  polythene , polyvinyl  chloride and polystyrene .

thermosetting plastics : plastics which once moulded into a shape do not become soft on heating and cannot be moulded again are called thermosetting plastics .

examples : bakelite , melamine and formica

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

bcde is the incorrect answer it is a
