प्रश्न
A given mass of water is cooled from 10°C to 0°C. State the volume changes you will observe. Represent these changes on a temperature-volume graph.
उत्तर
When water is heated from 0°C to 4°C, its volume first falls; when it is heated further from 4°C to 10°C, its volume grows. Thus, at 4°C, the water volume is at its lowest.
The following temperature-volume graph indicates how the volume of water changes from 0°C to 10°C:
