Detailed explanation-1: -When 1 liter of water is cooled from 4°C to 0°C, the volume of water begins to increase due to the unique property of water known as ‘Anomalous Expansion of Water. ‘
Detailed explanation-2: -Answer: Solution: Though liquids expand on heating, water does not expand between 0°C to 4°C instead it contracts as water has maximum density at 4°C. It expands above 4°C.
Detailed explanation-3: -When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.
Detailed explanation-4: -4 degrees C turns out to be the temperature at which liquid water has the highest density. If you heat it or cool it, it will expand. The expansion of water when you cool it to lower temperatures is unusual, since most liquids contract when they’re cooled.
Detailed explanation-5: -Water on heating from 0 ∘C to 4 ∘C contracts and on further heating it expands. This is called anomalous expansion of water.
