When shall you call it is ice instead of water?

The state of \(H_2O\) molecules is depicted in Fig. 1 at three different times. In Fig. 1 (a), the overall structure of the system is clearly organized, as demonstrated in Fig. 2. As we increase the temperature of the system, the atoms begin to vibrate and some of the characteristic structures of ice start to break down, as shown in Fig. 1 (b). If the temperature continues to rise, the entire system becomes increasingly chaotic.
