At 277 K or (4 degree celsius), it so happens that the entire cage like structure is broken which results in decrease in volume resulting in maximum density. Therefore, density of water is maximum at this temperature

heya!
At 0°C, due to presence of large air gaps, density of ice is less. When we increase tempreture, few hydrogen bonds break and water molecules get closer and fill the air gap, and so density gradually increases and becomes maximum at 4°C or 277K. Above 4°C, due to increase in kinetic energy, the water molecules moves apart and density again decreases and thus, water has maximum density at 4°C.
I hope it helps!!
