But water is denser than ice so between that range, the density should decrease first
The correct answer here is A, cuz at 0⁰c water still
contains ice particle which is less dense that
liquid water. as heat is applied it contracts and
there is a rise in density per degree rise in
temperature till about 4⁰c (where water has it's
maximum density) and from there, the density
drops again. Basic anomalous behaviour of
water . So the density increases for a while, then
decrease
The selected answer is wrong:
usually, when a substace is heated, it expands but water behaves in an anomalous state thereby causing it tocontract when cooled from about 4-0 degrees thereby increasing its density. think am.
The selected answer is wrong because
From 4°-0° the density of water increases but
From 0°-4° density of water decreases
Since water has its lowest density @4°c
