Which of the following is a ceramic material?
steel
glass
cement
polythene
Pottery and china are suitable for making tea pots because they are:
brittle
transparent
heat insulators.
non-conductors of electricity
Which of these statements about the formation of solid crystals is correct?
Rapid cooling produces the largest crystals as the atoms quickly form molecules.
Slow cooling produces the largest crystals as the atoms have time to form a regular lattice.
Rapid cooling produces the largest crystals as it allows more bonds to form in the lattice.
Slow cooling produces the largest crystals as the atoms can form lots of molecules.
Which of the following shows a substance that would have a high melting point but a brittle structure?
Which of the following is a synthetic polymer?
sand
rubber
concrete
PVC
A polymer is formed when:
monomers join together in chains.
molecules break up into large atoms.
single atoms join to make monomers.
long chains break up to form molecules.
Some polymerisation reactions are endothermic. What does this mean?
The polymers are made by burning oil.
The formation of the polymers transfers heat into the surroundings.
The polymers are made by breaking up long chain molecules.
The formation of the polymers makes the surrounding temperature decrease.
The diagram shows how the atoms in the rubber chains are joined together in natural rubber. Vulcanisation is the process of adding cross-links to sulfur. How does this process change the natural properties of the rubber?
It makes the rubber softer but it is still easy to melt.
It makes the rubber harder and easy to melt.
It makes the rubber harder but it is still elastic
It makes the rubber more flexible and easier to melt.
Which of the following is a composite material?
glass
plywood
poly(styrene)
silicon dioxide
Why is concrete described as a composite material?
because it is made with cement
because it sets hard and is strong
because it combines two or more materials
because it is made by mixing lots of different materials with water
Glass reinforced plastic is used for building boats because it is:
flexible and strong.
strong and brittle.
brittle and an insulator.
an insulator and transparent.
Which of the following describes what happens during the decomposition of calcium carbonate (limestone) to make calcium oxide (lime)?
Heating makes two compounds join together by an endothermic reaction.
Heating makes two compounds join together by an exothermic reaction.
Heating breaks up the compound by an exothermic reaction.
Heating breaks up the compound by an endothermic reaction.
Which of the following substances is thought to be one of the main greenhouse gases responsible for Acid rain?
soot
water
sulfur dioxide
carbon dioxide
Which of the following explain what a non-biodegradable polymer is?
a polymer that breaks down when buried in the soil
a polymer that burns in air to form carbon dioxide and water
a polymer that doesn’t break down when buried in the soil
a polymer that does not burn when heated in air
Which of the following best explains why low levels of toxins released into the sea by factories can cause serious problems to humans?
The toxic materials release heat, which is causing global warming.
The toxin levels increase in the larger animals up the food chain.
The toxin levels in the water increase as the toxin molecules react.
The toxins increase acid levels in the water and damage water life.
Which of the following would help reduce the possibility of global warming occurring?
Burn less fossil fuels.
Remove sulfur from all fuels.
Use more biodegradable plastic bags.
Remove all toxic materials from factory waste.
How are landfill sites used to deal with waste materials?
They burn the waste to produce energy.
They spread waste on or bury it in the ground.
They sort most of the waste items so they can be reused.
They melt the waste together to form large solid blocks of material.
Recycling a metal will help us be able to use that metal further into the future because:
recycled metals cost less.
it won’t use up landfill space.
recycled metal objects usually last longer.
recycling saves our reserves of metal ores.
Which of the following materials is recycled, by crushing and grading, to make aggregate for building foundations?
paper
wood
conrete
polythene
The most important reason for recycling glass is that it saves large amounts of:
sand
trees
energy
limestone
