Natural materials used in industrial processes

Question 1

C

element base for lots of materials e.g. carbon fibres, graphite, graphene, diamond

Answer 1

carbon

Question 2

carbon allotrope

_______ is very strong, colourless material with a very low electrical conductivity.

Answer 2

diamond

Question 3

carbon allotrope which is 1 atom of graphite

Material discovered in the early years 2000 (Nobel prize for Physics 2010)

Answer 3

graphene

Question 4

carbon alotrope

______ is a very good conductor, is the most thermodynamically stable form

Answer 4

graphite

Question 5

a hydrocarbon diene monomer.
The material properties of natural rubber make it an elastomer and a thermoplastic. However it should be noted that as the rubber is vulcanized it will turn into a thermoset. Most rubber in everyday use is vulcanized to a point where it shares properties of both i.e. if it is heated and cooled it is degraded but not destroyed.

Answer 5

natural rubber

Question 6

or rosins
hydrocarbon secretion of many plants, particularly coniferous trees, valued for its chemical constituents and uses such as varnishes*, adhesives, as an important source of raw materials for organic synthesis for instance.

Answer 6

resin
