Contract.
Frozen water expands, while other frozen liquids contract.
yes, because the cooling process removes energy from the matter which makes the particles move less and the matter contract
Mostly they expand as they warm, contract as they cool.
No. The rate of expansion/ contraction varies from one material to the next.
for A+ true
yes

Contract.
At night, there is no sun, thus there is no heat. When there is no heat, solids contract. The wires, being solids contract at night and in the morning, when there is heat, they sag.
No, because fire is buring gases. If the gases were frozen (therefore solids), it wouldn't make fire.

yes they do
By applying heat
