PPT-Chemical and Physical Features of Seawater

The Waters of the Ocean 1 A molecule of water is made of two hydrogen atoms and one atom of oxygen 2 Water molecules are held together by hydrogen bonds weak and easily broken 3 The statesphases of water are . CS Mexico INTRODUCTION INTRODUCTION About 75 of Earth s surface is water of this quantity Saltwater oceans hold 9725 of surface water and only 3 is fresh water but only 07 it is available for human use from rives streams lakes ground water etc The o CS Mexico INTRODUCTION INTRODUCTION About 75 of Earth s surface is water of this quantity Saltwater oceans hold 9725 of surface water and only 3 is fresh water but only 07 it is available for human use from rives streams lakes ground water etc The o First lecture:. 1.

Mrs. Lowe . April 2011. Chemical changes . Chemical change . is a change that forms a new type of matter . Chemical property . is a feature of matter that can cause a chemical change. Examples of a different type of matter forming during a chemical change. 70% of the Earth is covered by . o. cean water!. Seawater Composition. Ocean water is made up of three things:. 1.) Dissolved Gases . 2.) Organic Molecules. 3.) Salts. Seawater is a solution.. Solution: Made of a solute and a solvent. . Part 5. Density Zones. The . ocean is broken . into . density zones. The 3 density . zones are controlled . by: . Temperature. salinity. Zone 1:. Surface . zone – the upper layer of the ocean, . least . and. Changes. By Jordan Parkinson. What are some Physical Properties?. Appearance – O. utward . or visible aspect of a person or thing. . Color - A. . visual attribute of things that results from the light they emit or transmit or reflect. Blue Color. Blue Color. Physical property. Density. Density. Physical property. Flammability. Flammability. Chemical property- The original substance is fundamentally changed. . Solubility- (dissolves into a liquid to make a solution). How to tell the difference. Physical properties. Inherent characteristics of a substance that can be determined without altering its composition. Associated with its physical existence. Color, taste, odor, state of matter (solid, liquid, or gas), density, melting point, boiling point.. World Ocean. 3.1 The Waters of the Ocean. A. The Unique Nature of Pure Water. . All matter is made of atoms. Elements are make from one kind of atom. A molecule is two or more different atoms combined. Oceans and Temperature. Ocean surface temperature strongly correlates with latitude because . insolation. , the amount of sunlight striking Earth’s surface, is directly related to latitude.. 1. Ocean currents carry warm water . Jorge A. Arroyo P.E.. Innovative Water Technologies. The State of Seawater Desalination in Texas. Texas i-Water 2010. Opportunities for seawater desalination. Texas i-Water 2010. Access to a plentiful source. S8P1d. Distinguish between physical and chemical properties of matter as physical (i.e., density, melting point, boiling point) or chemical (i.e., reactivity, combustibility) How are physical and chemical properties different? Physical and Chemical Changes Physical and Chemical Properties Everything around us has physical and chemical properties. Physical Properties Characteristics you can observe without changing the substance into something new.
