(a) What is meant by the anomalous expansion of water?
(b) Draw a labelled sketch of the qualitative variation of density of water with temperature from 0 °C to 10 °C.
(c) Explain, with the help of the behaviour shown in part (b), why aquatic organisms can survive in a deep pond even when the surface water has frozen.
(d) State and explain two consequences that would follow for life on Earth if water did not exhibit anomalous expansion in the range 0 °C–4 °C.
