In ice, water molecules are arranged in a repeating pattern that gives ice its crystal structure. Even though ice is at 0 °C, the molecules still vibrate. After freezing, the water molecules are ...
Students could go on to investigate the relationship between hydrogen bonds and surface tension, the anomalous density of ice and the role of hydrogen bonds in maintaining the shape of DNA ...
The study shows that this ice was apparently also behind the formation of organic molecules, including all intermediaries in the Krebs cycle. The Krebs cycle is a series of chemical reactions that ...
