The anomalous expansion of water refers to its unusual property of expanding when cooled below 4°C and reaching its maximum density at 4°C. This behavior is contrary to most substances, which contract and become denser as they cool below their freezing point.
8 gru 2015 · The origin of the anomalous properties of water is the increase in structural fluctuations, as water is cooled down and approaches the Widom line, leading to fluctuations into tetrahedral...
The anomalous properties of water are those where the behavior of liquid water is entirely different from what is found with other liquids [1414]. a The counterintuitive anomalies of water mostly arise from the properties of its hydrogen bonds, that also produce and control the local tetrahedral arrangement of the water molecules.
2 kwi 2014 · Nature Communications - Water shows various anomalies, but an understanding of their microscopic origin is still missing. Russo and Tanaka introduce a new structural order parameter in...
Anomalous expansion of water is an abnormal property of water. It occurs only between 4°C to 0°C whereby it expands when cooled, and contracts when heated...!
Explanation for Anomalous behaviour of water. At 4°C, water has Maximum density. Normally, liquids contract on cooling & the density increases. However, water is special. It contracts when cooled, down to a temperature of 4°C (normal behaviour).Water attains its maximum density at 4°C .
This exceptional behaviour of water in respect of expansion within the range of 0°C to 4°C, is called anomalous expansion of water. The two graphs below represent the change in volume and density of 1 g of water, with the increase in temperature [Fig.]
