Answer:
Polymers are the naturally occurring or synthetic macromolecules that are composed of repeating subunits, called monomers.
The three main classes of polymers are: thermoplastic, thermosetting, and the elastomers.
Thermoplastic polymers have linear bonding. These polymers can be melted again and thus can recycled.
Thermosetting polymers have cross-linked bonding. These polymers decompose when heated and thus can not be remelted and recycled.
Elastomers have linear bonding with some cross-linking. These polymers extreme elastic extensibility and thus can revert back to its original shape after deformation, without causing any permanent damage.

Answer: Temperature T = 218.399K.
Explanation:
Q= 129W/m2
σ = 5.67 EXP -8W/m2K4
Q= σ x t^4
t = (Q/σ)^0.25
t= 218.399k
