Viscosity of Liquids Part I: Low Viscosities Mona Kanj Harakeh 1 Objectives • To measure and analyze the viscosities of ideal (Toluene/p-Xylene) and nonideal (Methanol/Water) binary solutions and their components. • To determine the Activation Energy to viscous flow. • The effect of temperature change on the viscosity will be studied. Method: The viscosities of liquids are determined by measuring the flow time for various liquids in an Ostwald viscometer. 2 Ostwald viscometer 3

Viscosity Investigation Research Question: How does the concentration of C6H12O6 affect the viscosity of a C6H12O6 solution? Hypothesis I believe that as the C6H12O6 concentration increases‚ so will the viscosity of the solution. I think so because the increased number of electrons caused by the greater mass of C6H12O6 will lead to stronger Van-der-Waals forces. Furthermore I believe that because of the increase of C6H12O6 particles‚ indicated by the increased number of moles of C6H12O6‚ there

The absurdity of the methanol economy I had not actually heard of it‚ but a colleague mentioned it in the course of conversation: George Olah‚ the Hungarian-born U.S. chemist whose research is focused on hydrocarbons‚ strongly advocates the introduction of methanol as a chemical energy carrier. The basic idea is that‚ to be sure‚ we need to find a replacement for the short chain alkanes that constitute the major part of gasoline‚ aviation spirit‚ etc.‚ and which are used as the source of motive

Viscosity of sweetened water Avery Safley Introduction: Have you ever wondered why your honey comes out of the bottle so slow? The answer to this is viscosity. Viscosity is the resistance of a liquid to flow. Every liquid exhibits this resistance to some degree. Therefore the more resistance shown‚ the higher the viscosity. It can be thought of as fluid friction‚ just as solids show friction between other solids. This friction is caused by the molecules within the substance. Viscosity is

Lab report: Viscosity of Liquids Introduction This experiment focuses on measurements of different trials of various concentrations. The collected data is used to compare and contrast to the ideal binary solutions and their components. The Ostwald viscometer is a useful laboratory equipment to measure the viscosities of many binary solutions. Background Molecules have the ability to slide around each other‚ result in a flow. Such a flow has a resistance called viscosity. Microscopically

examine the viscosities of ideal and non-ideal solutions. The ideal being the toluene/p-xylene and the non-ideal being the methanol/water. The second objective of this lab was to investigate the temperature dependence of viscosity (Halpern‚ 17-1). Introduction: Viscosity is the resistance to flow of a certain fluid. In this experiment two solutions are used. According to the definition of viscosity mobile liquids have a relatively low viscosity. Fluidity is the reciprocal of viscosity‚ given

Viscosity Science Lab Purpose: To determine of changing the viscosity will affect the time it takes for a marble to flow through a liquid. Hypothesis: If a marble is dropped into dish soap and corn syrup‚ than I predict that the marble in the dish soap will travel faster than the marble in the corn syrup because I know that the viscosity of the corn syrup is thicker than then the viscosity of the dish soap. Also‚ the particles in the corn syrup are more compact than those in the dish soap

1 LAB SHEET - VISCOSITY OF GLYCERINE Aim: To measure the viscosity of glycerine using Stokes ’ method in which steel balls are allowed to fall through glycerine. Theory: (i) If a body of mass m falls through a viscous fluid‚ it will accelerate until the combination of the viscous force (or drag) FD‚ and the buoyancy force FB balance the gravitational force Fg (= mg) FD + FB = Fg (1) When this equilibrium is reached‚ the body continues to fall‚ but at a constant velocity‚ called the terminal
