Pick out the wrong statement?
A Pure rubber is as useless as pure gold as a material of construction
B Thermal conductivity of aluminium is higher than that of copper; hence it is increasingly used for utensil making
C Copper has poor weldability
D Reinforced plastics are made from both thermoplastic as well as thermosetting plastics
Correct Answer: Thermal conductivity of aluminium is higher than that of copper; hence it is increasingly used for utensil making

B Wrought iron cannot be easily forged and welded
C The chilled cast iron does not contain graphite
D Spheroidal grey cast iron contains graphite flakes
Correct Answer: Wrought iron cannot be easily forged and welded
Pick out the correct statement?
A Stainless steel is nothing but chromium coated steel
B Hardening of a soft metal can be done by alloying it with another metal or non-metal
C Plastic deformation of a material is its temporary distortion under the action of applied stress
D Rusting of iron is not electrochemical in nature
Correct Answer: Hardening of a soft metal can be done by alloying it with another metal or non-metal
Pick out the wrong statemen?
