Detailed explanation-1: -Water has maximum density at 4 degree celsius.
Detailed explanation-2: -Density is measured as mass (g) per unit of volume (cm³). Water is densest at 3.98°C and is least dense at 0°C (freezing point). Water density changes with temperature and salinity.
Detailed explanation-3: -Detailed Solution. An especially notable irregular maximum density is that of water, which reaches a density peak at 3.98 °C (39.16 °F).
Detailed explanation-4: -When water is at 0 ° C, it takes a cage-like structure, and thus the volume increases which results in the density decrease. The temperature of the water increases and gets to 4 ° C, here, the density is maximum. The reason behind this is that the cage-like structure starts to break and come closer.
