Materials Science Vocabulary Quiz
12 multiple-choice questions on materials science vocabulary: polymers, alloys, tensile strength, composite materials, semiconductors, corrosion, ductility and nanotechnology. B2 level.
This quiz focuses on how the target vocabulary for Materials Science is actually used in context at B2 level, rather than testing bare definitions. Correct answers you will need to identify include terms such as polymer, alloy, tensile, composite and corrosion, each embedded in a full example sentence so you have to judge meaning from context, not just recognise an isolated word.
Working through all 12 questions and checking the explanations in the FAQ below is a quick way to spot any terms you are still unsure of. Revisiting the quiz again after a day or two, rather than only once, is one of the most reliable ways to move new vocabulary from passive recognition into words you can use confidently yourself in speaking and writing.

Materials Science Vocabulary — FAQ
What is a 'polymer' in materials science?
A polymer is a large molecule made of many repeating units (monomers) linked by covalent bonds. Polymers can be natural (rubber, cellulose, DNA) or synthetic (polyethylene, nylon, PVC). Their properties depend on molecular structure and chain arrangement.
What is an 'alloy'?
An alloy is a mixture of two or more elements, at least one being a metal, designed to have superior properties. Steel is an alloy of iron and carbon; brass is copper and zinc; bronze is copper and tin. Alloying improves strength, hardness, corrosion resistance or conductivity.
What is 'tensile strength'?
Tensile strength is the maximum stress a material can withstand while being stretched before it breaks, measured in megapascals (MPa). It is key for cables, reinforcing bars, aerospace components and other applications where materials are pulled or stretched.
What is a 'composite material'?
A composite material combines two or more constituent materials to achieve properties superior to either alone. Examples include carbon fibre reinforced polymer (CFRP), fibreglass, reinforced concrete and plywood. Composites offer high strength with low weight.
What is 'corrosion' in materials science?
Corrosion is the gradual deterioration of a material, usually a metal, through chemical or electrochemical reactions. Rusting of iron is the most common example. Prevention methods include coatings, galvanising, corrosion-resistant alloys and cathodic protection.
What is a 'semiconductor'?
A semiconductor has electrical conductivity between a conductor and an insulator. Silicon is the most common. Conductivity is controlled by doping (adding impurities). Semiconductors are the foundation of transistors, integrated circuits, solar cells and LEDs.
What is 'nanotechnology' in materials science?
Nanotechnology manipulates matter at the 1–100 nanometre scale, where materials exhibit unique properties due to quantum effects. Applications include self-cleaning coatings, drug delivery, nanocomposites with enhanced strength and carbon nanotubes in electronics.
What does 'ductility' mean?
Ductility is a material's ability to be drawn into wires or deformed under tensile stress without fracturing. Gold and copper are highly ductile. It differs from malleability (ability to be hammered into sheets) and is important for electrical wiring.
What is 'thermal conductivity'?
Thermal conductivity is a material's ability to transfer heat, measured in watts per metre kelvin (W/m·K). Metals such as silver, copper and aluminium conduct heat well. Insulators like wood, foam and air have low thermal conductivity.
What is 'fatigue' in materials engineering?
Fatigue is the weakening of a material caused by repeated cyclic loading, even below its ultimate strength. Tiny cracks initiate at stress concentrations and grow until sudden fracture. Fatigue failure affects aircraft, bridges and vehicle components.
