Water on heating from 0 ∘C to 4 ∘C contracts and on further heating it expands.
True
False
Water on heating from 0 ∘C to 4 ∘C contracts and on further heating it expands.This is called anomalous expansion of water.
Water is cooled from 4∘C to 0∘C. It :
(a) contracts (b) expands
(c) first contracts, then expands
(d) first expands, then contracts.
