How is aquatic life benefitted by the fact that water has the maximum density at 4C?

Solution

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 4C i.e. it contracts, however when chilled additionally off from 4C to 0C it acts anomalously i.e. it grows as opposed to contracting further. So ice at 0C is less thick than water at 4C



At the point when a lake begins getting cool the water at the best hits 4C winds up plainly thick and sinks to the base, this continues occurring until the point when all water in the lake has achieved 4C. Presently when the temp outside drops encourage the water at the best hits 0C 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 4C where sea-going life can survive

The maximum density of water occurs at 4C 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
