Question

what conclusion could you drawn from the graph ? how is anomalous behaviour of water proved?

Answer 1

when a liquid is heated upto a certain temperature, it expands, and when cooled it contracts. Water, however, shows a special and exceptional behaviour. If we heat water from 0 °C upto 4 °C, it contracts instead of expanding. At 4 °C its volume is minimum (due to contraction). If the water is heated further, it expands and its volume increases. The behaviour of water between its temperature from 0 °C to 4 °C is called anomalous behaviour of water.

Answer 2

The conclusion that we can draw from the anomalous behaviour of water is that waters volume decreases and density increases while dropping of temperature till 4° c but after that the density deceases and volume increases
