    double bond among the carbon atoms‚ the fatty acid molecule is unsaturated. What form does each of these fats take at room temperature and what are the common sources of each? Saturated fats are solid at room temperature and unsaturated fats are liquid at room temperature. A common source of saturated fat is tallow‚ lard‚ and butter. Common sources of unsaturated fat are canola oil‚ corn oil cottonseed oil‚ and soybean oil. What is your hypothesis? I believe that we will extract less saturated

    early “cooking” methods‚ modern separation involves piping oil through hot furnaces. The resulting liquids and vapors are discharged into distillation towers‚ tall‚ narrow columns that give refineries their distinctive skylines. Inside these towers‚ the liquids and vapors separate into components or fractions according to weight and boiling point. The lightest fractions‚ including gasoline and liquid petroleum gas (LPG)‚ vaporize and rise to

Examples: Glass‚ Rubber Liquids flowing freely but of constant volume. Examples: Water‚ Mercury‚ Alcohol Viscosity-a measure of its resistance to gradual deformation by shear stress or tensile stress. Surface tension-the force that acts on the surface of a liquid and tends to minimize the surface area. Surface tension can

    EMULSION An emulsion is a mixture of two or more liquids that are normally immiscible ( non mixable). Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used interchangeably‚ emulsion should be used when both the dispersed and the continuous phase are liquids. In an emulsion‚ one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include milk‚ mayonnaise

    Volcanoes Have Different Characteristics? A. Formation of Lava Magma is formed by melting preexisting rock in Earth’s interior For magma to rise through crust it must be: (1)less dense than the crust (2) runny enough to flow (3) hot enough to stay liquid Magma that cools to form solid rock = lava B. Composition of Magma/Lava Magma is composed of various proportions of: Oxygen‚ Silicon‚ Aluminum‚ Iron‚ Calcium and Potassium Mineral – naturally occurring element or compound that has an ordered internal

    the oil has left. Oil’s function is to lubricate‚ clean‚ and cool the engine. Additives are added to the oil to enhance those functions.Viscosity: Technically‚ viscosity is defined as resistance to flow. Commonly though‚ we think of it as an oil’s thickness. To be more specific‚ it is the thickness of an oil at a given temperature.The viscosity of an oil could be reported at any temperature‚ but to standardize things‚ most laboratories report either a low temp (100F or 40C) or a high temp (210F or 100C)
