At what temperature does the water have the highest density?

0°C (32°F)
100°C (212°F)
-273°C (-459.4°F)
4°C (39.2°F)
In­creas­ing the tem­per­a­ture gen­er­al­ly de­creas­es the density, but water is a notable ex­cep­tion: the density of water in­creas­es between its melting point at 0 °C and 4 °C. Similar behavior is observed in silicon at low tem­per­a­tures.
