What is the difference between Thermoplastics and Thermoset polymers? A)Thermoplastics can be moulded to shape, thermoset cannot. B)Thermoplastics have covalent bonds that can be broken and reformed, thermoset does not. c. Thermoplastics have entangled polymerics units that can be untangled at elevated temperature, thermoset does not. d. Thermoset plastics are more flexible then thermoplastics. Q )What is/are the benefit(s) of short fibre reinforcements? A)Increased stiffness only. B)Increased strength and increased Toughness. C) Increased Toughness and increased flexibility. D) None of...

a) Distinguish between processing of thermoplastics and thermoset polymers to make a final product (the process is not to make the polymer, but to make the final product) and relate this to the microstrucural differences of he polymers. b)Using the concept of the relation between glass transition temperature and stucture, explain why polyethylene is ductile at room temperature whereas polystyrene is brittle at room temperature.

A mixture of water and graphite is heated to 600 K. When the system comes to equilibrium it contains 0.13 mol of H2, 0.13 mol of CO, 0.43 mol of H2O, and some graphite. Some O2 is added to the system and a spark is applied so that the H2 reacts completely with the O2. Find the amount of CO in the flask when the system returns to equilibrium. Express your answer to two significant figures and include the appropriate...

A mixture of water and graphite is heated to 600 K . When the system comes to equilibrium it contains 0.11 mol of H 2 , 0.11 mol of CO , 0.31 mol of H 2 O , and some graphite. Some O 2 is added to the system and a spark is applied so that the H 2 reacts completely with the O 2 . Find the amount of CO in the flask when the system returns to equilibrium.
