1. Water is a polar molecule, meaning it has a slightly positive charge on one end and a slightly negative charge on the other. This allows water molecules to form hydrogen bonds with each other and with other polar molecules.
2. Water has a high specific heat capacity, meaning it can absorb and release a large amount of heat energy without a significant change in temperature. This property helps regulate Earth's temperature and allows living organisms to maintain a stable internal temperature.
3. Water has a high heat of vaporization, meaning it requires a large amount of energy to change from a liquid to a gas. This property allows water to absorb heat from its surroundings when it evaporates, helping to cool the environment.
4. Water is a good solvent, meaning it can dissolve a wide variety of substances. This property is essential for many biological processes, as it allows nutrients and waste products to be transported throughout the body.
5. Water has a high surface tension, meaning it forms a "skin" on its surface that resists external forces. This property allows small organisms, such as insects, to walk on water and helps water move through plants via capillary action.
6. Water is amphoteric, meaning it can act as both an acid and a base. This property allows water to participate in chemical reactions and maintain a stable pH level in living organisms.
