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

Many people habitually the dryer and dehydrator is the same kind of equipment‚ in fact there is a difference between the two machines. Some manufacturers also know the difference‚ but consumers and customers that they had to perceptual habits so "brainless" sales. Industrial dryer includes rotary dryer machine‚ slime dryer‚ fly ash dryer and cylinder dryer. Generally‚ these industrial dryers have these common features: First‚ automatic. Dryer machine can be set time by automatic controlled device

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 as equation 1: F=1/ η. Fluidity is advantageous because solutions of mixed solutions of nonassociating liquids are roughly additive. In this experiment binary solutions are used‚ so if each pure liquid has fluidities Fa and Fb‚ the fluidity of a mixture is given by: Equation1 (Halpern‚ 17-3).

solution C ABSTRACT Liquid C and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract‚ followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119.0C while the boiling point of liquid C was found to be 117C

Rate of Evaporation of Different Liquids Objective of the Project This project is of the rate of evaporation of different liquid‚ in which we also discuss the factors which affect the rate of liquid. Introduction When liquid is placed in an open vessel. It slowly escapes into gaseous phase ventually leaving the vessel empty. This phenomenon is known as vaporization or evaporation. Evaporation of liquids can be explained in the terms of kinetic molecular model although there

Calculating the Density of Liquids II. Purpose/Background: The purpose if this lab was to determine the density of water and an unknown liquid. Density is defined as the mass of a substance divided by its volume. It is an intrinsive property of matter and is used to specifically characterize substances. III. Procedure: 1.We massed an empty 10mL graduated cylinder to the nearest .01g. 2.Then‚ we filled the graduated cylinder with 4.0-5.0 mL of distilled water‚ 3.massed it to the nearest 0.1

March 2‚ 2011 Lab Report Physical Properties of Two Types of Solids SCH3U0 Maggie Liu Abstract The purpose of this lab is to study some of the physical properties of two types of solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour‚ hardness‚ melting point‚ solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours‚ hard‚ a
