Physics
A given mass of water is cooled from 10°C to 0°C. State the volume changes observed. Represent these changes on a temperature-volume graph.
Answer
On cooling water from 10°C, the density of water first increases up to 4°C and then decreases on cooling further below 4°C to 0°C.
Hence, the density of water is maximum at 4°C which is equal to 1 g cm-3 (or 1000 kg m-3 )
Temperature-Volume graph showing these changes is given below:
