Water has a number of unique properties that sets it apart from other substances, sometimes called the "anomalies of water." The most commonly recognized anomalies are:
Pick 1 of these properties and learn more about how it can be explained from the viewpoint of attraction forces between molecules and/or other physical properties of water, as well as the significance of these properties for life on earth.
Based on the information you have learned, write a thread about 1 of the anomalies, referencing your sources and address the following points:
