Answer
Identify the correct graph showing the variation in the volume of water with temperature. Heat and Energy, Concise Physics Solutions ICSE Class 9.

Reason — The volume of water first decreases on heating it from 0°C to 4°C and then increases on further heating it from 4°C to 10°C. The volume of water is thus minimum at 4°C.
