Physics: Anomalous Expansion of Water

Anomalous expansion of water

Anomalous expansion of water

This means something that is unusual. The temperature range of water from 0°C to 4°C is unlike most substance because is volume decreases as the temperature increases. 

From 0°C to 4°C,  water experiences an adnormal property whereby it expands instead of contract. It also becomes less dense.

Fishes and Anomalous Expansion of water 

The temperature within the water is very important to fishes, as it depicts their survival. The expansion of ice from the liquid state keeps a fish floating at the top of water, but during expansion from 0°C to 4°C, fishes tend to float to the bottom

Above 4°C, water behaves normally because its volume increases s the temperature increases. Water has a minimum volume from density at 4°C. The decrease of volume when the temperature increases from 0°C to 4°C is called anomalous expansion.
