At which point water has maximum density?

Water has maximum density at 4 degree centigrade. Water (H2O) is the most abundant compound on Earth’s surface, covering about 70%. In nature, it exists in liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at standard temperature and pressure. At room temperature, it is a tasteless and odorless liquid, nearly colorless with a hint of blue.
