The boiling point of water is high, which is due to breaking the hydrogen bonds that break the molecule need more energy. When the water is heated, the destruction of the hydrogen bond is not regular, and sometimes the hydrogen bond is self-reorganized, producing a "empty hole" that is not connected to any water molecules. It is believed that as the water temperature rises and more hydrogen bonds are destroyed, the empty holes will become large until the hydrogen bond network is destroyed, and the water molecules have become evaporated, but no one can confirm this. Now, Dilk Chan, the Max Plancock Solid Chemical Physics Research Institute, Germany, using a computer to simulate 256 water molecules, and studied the early situation in the process of water. He found that the small holes next to each other will be merged into a larger void to make the water molecules "escape" from the network. In the end, the network is completely destroyed, and the water turns into water vapor. During the simulation process, the process of simulated a water molecules becomes water vapor is less than 10 billion.
