the Molar Mass of an Unidentified Volatile Liquid Abstract Molar mass helps to determine how much of a substance is present in a sample. Volatile liquids change from liquid to gas at relatively low temperatures and atmospheric pressures. In this investigation an unknown volatile liquid is vaporized so that the ideal gas law can be used to determine its molar mass. This study will apply the ideal gas law in tandem with the concept of volatile liquids and basic molar mass related stoichiometry to

INTRODUCTION: A high Reynolds number Newtonian liquid jet‚ exiting a two-dimensional channel‚ is examined in this study. Fully developed Poiseuille flow‚ driven by an applied pressure gradient‚ is assumed to prevail upstream of the channel exit. Flow is assumed to be laminar‚ steady and incompressible. A free surface develops as the fluid exits the channel. The resistance of the air on the free surface of the liquid jet can be neglected so that‚ the shear stress at the channel wall disappears and

3.3. Characterization of the S2 VNP loaded liquid SNEDDS 3.3.1. Assessment of self-emulsification efficiency The emulsification time for S2‚ which is the time needed for SNEDDS to form homogeneous transparent mixture upon dilution‚ was 12 sec when 1 gm of VNP SNEDDS was added to 200 ml of 0.1 N HCl. When the same experiment was performed but by using 500 ml distilled water‚ the time required for the complete disappearance of SNEDDS was 14 sec. The emulsification in both media is under grade A of

water came from outer space to Earth. The water was brought to the planet for the comets. The water has a different structure for each state (gas‚ liquid‚ ice). Liquid water has random molecules. On the other hand‚ the ice has a more stable structure. The different structure between ice and liquid water can explain why the ice has less density than liquid water. Temperature is responsible for increasing the dissolution of components‚ and electrical conductivity. Pure water is not a good conductor‚

Acetone/Chloroform Liquid-Vapor Phase Diagram Abstract: Liquid-vapor phase of acetone/chloroform was studied through distilling a series of mixtures with different mole fraction. When the mixtures were boiling‚ their vapor was condensed through a water column and collected in a receiving container. Refractive index was collected for starting mixture‚ distillate and residue for each sample. A boiling temperature versus acetone’s mole fraction was constructed to show the liquid-vapor phase diagram

Determining the accuracy of varieties of pipettes by weighing and finding the density of a liquid Abstract Different varieties of pipettes (P100‚ PR1000 pipettors and a serological pipette) along with a weighing balance was used in this investigation to check the density of an unknown liquid by first finding out what the liquid weighed and plotting a graph of the mass in grams against the volume of the liquid used in micro litres (µl) and finding the gradient of the graph (∆Y/∆X). Most of the standard

OF DETTOL ANTISEPTIC LIQUID ON THE GROWTH OF E.COLI Background: Escherichia coli are rod shaped‚ gram negative bacteria often found in the gut of humans and other warm-blooded mammals (Jacques & Ngo‚ 2004). It is transmitted primarily through faecal contaminated food and water. Most strains of E. coli are not harmful to humans‚ however some strains are pathogenic and can cause symptoms including diarrhoea (Unknown‚ 2012). The active ingredient in Dettol Antiseptic Liquid is 4.8% chloroxylenol

The 21st Century Energy Solution: Liquid Flouride Thorium Reactor Recently the spotlight has been set on renewable energies to assist with weaning off of greenhouse gas emissions‚ solving issues with energy independence‚ and to exploit their inherent renewability. Unfortunately our technology is not quite up to speed economically with our wish to rely completely on renewable energy‚ thus many non-renewable energies are recognized as viable options to power our economy (Fraser‚ 2011).

Thermometer Works - pg. 23 Purpose: What makes the liquid within a thermometer go up and down? Hypothesis: If the liquid is placed into objects of different temperatures‚ then the liquid moves up in the hotter substance and down in the colder substance‚ because of the change in the molecular energy when the water is hot and when the water is cold.
