A Level:
Air is usually classified as a homogeneous mixture. Explain a scenario that could cause a
sample of air to become a heterogeneous mixture giving reasoning to support your
answer.
Classify copper’s property that it is a good conductor of heat as physical or chemical, as
well as extensive or intensive and give reasoning to support your answer.
