Which of the following statements is true for water when it is cooled from 4°C to 0°C?
Volume increases but density decreases
Water shows anomalous expansion between 4°C and 0°C: as it cools in this range, its volume increases while its density decreases (reaching maximum density at 4°C).
The other combinations of volume and density change do not correctly describe this anomalous behaviour of water.
Hence, 'Volume increases but density decreases' is the correct answer.
