Water is cooled from 4∘C to 0∘C. It :
(a) contracts (b) expands
(c) first contracts, then expands
(d) first expands, then contracts.
Water is cooled from 4oC to 0oC. It will :
When water cools, first it expands in volume but below 4°C it starts contracting until it reaches 0°C.
Water on heating from 0 ∘C to 4 ∘C contracts and on further heating it expands.
