Question

At what temperature is the density of water maximum?

Answer 1

1. If the water at $0°C$is heated, its volume decreases until the temperature reaches$4°C$.
2. Above$4°C$ water behaves normally, and its volume increases as the temperature increases.
3. At $4°C$, the density of water is greatest.
4. This behavior of water is called its anomalous behavior.

So the temperature at which the density is maximum at $4°C$.
