How is aquatic life benefitted by the fact that water has the maximum density at 4∘C?
Typical conduct for a fluid is to develop warming and contract on cooling. A fluid that agreements are said to end up noticeably thicker.
Water carries like an ordinary fluid when it's chilled off to 4∘C i.e. it contracts, however when chilled additionally off from 4∘C to 0∘C it acts anomalously i.e. it grows as opposed to contracting further. So ice at 0∘C is less thick than water at 4∘C
At the point when a lake begins getting cool the water at the best hits 4∘C winds up plainly thick and sinks to the base, this continues occurring until the point when all water in the lake has achieved 4∘C. Presently when the temp outside drops encourage the water at the best hits 0∘C bad swings to ice however since ice at the best is less thick than the water at the base it doesn't sink, so notwithstanding when you see a lake solidified at the best the water underneath is still at 4∘C where sea-going life can survive
The maximum density of water occurs at 4∘C because, at this temperature two opposing effects are in balance. Explanation: In ice, the water molecules are in a crystal lattice that has a lot of empty space. When the ice melts to liquid water, the structure collapses and the density of the liquid increases
