The unique properties of water are uncharacteristic of a molecule of such a small size. A solvent is simply a substance that can dissolve other molecules and compounds, which are known as solutes. when water breaks apart an ionic compound into cations and anions: when water surrounds substances that have been "broken apart": when water breaks down substances and surrounds individual molecules or particles: The attraction forces between mercury atoms in liquid mercury are stronger than the intermolecular forces between water molecules. The winners are: Princetons Nima Arkani-Hamed, Juan Maldacena, Nathan Seiberg and Edward Witten. These include: Cohesion, Adhesion, High surface tension, High specific heat, High Heat of vaporization, and the fact that ice floats (Ice is less dense as a solid than liquid water). Evaporation: When the temperature raises high enough, the water particles begin to move faster and gain more kinetic energy. After many, many years, you will have some intuition for the physics you studied. Five reasons water is so important to your health. Suppose oxygen was much less electronegative than it is, so that hydrogen-oxygen bonds were much less polar and hydrogen bonds could not form between water molecules. d. All of these. As a result, the middle part of the molecule near oxygen has a negative charge, and the other parts of the molecule have a positive charge. On a large scale, the Earth is 75% water. we saw earlier have an area of 3.00cm23.00 \mathrm{~cm}^23.00cm2 and are separated by a 2.502.502.50-mm-thick sheet of dielectric that completely fills the volume between the plates.

Surface tension allows the water to hold up materials heavier than itself. The human body uses water in all its cells, organs, and tissues to help regulate its temperature and maintain other bodily functions. As shape is critical for biochemical processes, this is also one of water's most important roles. Water molecules stick to other water molecules because of the weak hydrogen bonds. The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. Water resists a change in temperature. .
