Properties of Water
By Modeste and Anna
Water is a colorless, transparent, odorless, tasteless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms. Water is one of the main sources needed on earth. You need water to survive and without it you will die. You can only go 7 days without water or else you'll die. Water is important to everyone.
There are 6 different properties of water. Polarity, Cohesion & Adhesion, Capillary Action, Surface tension, High specific heat, and Universal solvent. Polarity is the property of having poles or being polar. It has a + and - end. Cohesion is an attraction or cohesive force is the action or property of like molecules sticking together, being mutually attractive. An example of cohesion is water falls from the sky as raindrops because they are together falling. Adhesion is the action or process of adhering to a surface or object. An example is adhesion is water clinging to the sides of a glass , Adhesion is add 2 things that are different, while cohesion is together doing the same thing. Capillary tension is the ability to flow in a narrow space. For example, a straw in a cup, the straw is narrow when a liquid is in it. Surface tension is tightness across the surface of H2O caused by cohesion due to polarity. An example is mosquitos running across water. High specific heat is The amount of heat needed to raise the temperature of one gram of a substance by one degree celsius, or to raise the temperature of one pound of a substance by one degree Fahrenheit. Universal solvent is water that is capable of dissolving a variety of different substances. Solvent => does the dissolving. Now you see the properties of water and the importance of water.
