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 have time to form a regular lattice

• 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

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
