2. Water is unique because the energy relationships of the water molecule are very important for us to understand in life. Whyis water unique??
3. When energy is added to the water the molecules speed up and are more freely to move around. When you have cold water the molecules slow down and they are tightly together. When the temperature gets warmer the energy in the molecules mover faster and they can go anywhere they want to because they have so much energy in the molecules or in simpler terms it dissolves.
4. A gram-calorie is- approximately equal units of heat, measured as the quantity of heat is required to raise the temperature of 1 gram of water by 1°C from a standard initial temperature and especially from 3.98°C, 14.5°C, or 19.5°C, at 1 atmosphere pressure. Also called small calorie. A common measure of heat energy is a gram-calorie. The amount of the heat needed to raise a gram of pure water from 14.5-degrees C. To 15.5-degrees C. at sea level air pressure. specific heat of water is one. All values of specific heat are related to the value defined by water. What is a Gram-Calorie?
5. Water exists in three phases which are: solid (ice), liquid (water), and gas (vapor). Ice has a rigid molecular structure which is held together by a strong bond between the molecules by the "hydrogen bond“. When heat is added to the ice it warms up until it reaches the freezing temperature of 32-degrees F. (0-degrees C.).
6. is a property of the surface of a liquid. It is what causes the surface portion of liquid to be attracted to another surface, such as that of another portion of liquid (as in connecting bits of water or as in a drop of mercury that forms a cohesive ball). What is Surface Tension??
7. Water serves as a lubricant Water forms the base for saliva Water forms the fluids that surround the joints. Water regulates the body temperature, as the cooling and heating is distributed through perspiration. Water helps to alleviate constipation by moving food through the intestinal tract and thereby eliminating waste- the best detox agent. Regulates metabolism Importance of water for humans..
