ABSTRACT A molecular diffusion experiment was conducted with the goal of determining the diffusion coefficient of acetone into air. For this experiment‚ acetone was placed in a capillary tube and was allowed to diffuse into non-diffusing air that was passed over the test tube at the temperature of 50oC.Thetemperature is kept constant and air stream is passed over the top of the tube to ensure that the partial pressure of the vapor is transferred from the surface of the liquid to be air stream bymolecular

Experiment 3: Cryoscopic Determination of Molecular Weight Aim: The primary objective of the experiment is to calculate the total molecular mass of the compound benzoic acid in a predetermined amount of cyclohexane. Introduction: One of the key concepts in this experiment is the term freezing point depression. The definition of this phrase is that when a solute is dissolved into a solvent‚ their collective boiling point will be less than that of the original boiling point of the solvent. This incidentally

electrical systems were designed for linear voltage and current waveforms (i.e. nearly sinusoidal)‚ excessive nonlinear loads can cause serious problems such as overheating conductors‚ transformer and capacitor failures as well as malfunction of electronic equipment. The magnitudes of harmonics generated by the CFLs vary between manufacturers and between ranges of lamps from the suppliers. At present‚ no serious power quality problems have been reported with the use of CFLs. One reason may be that

Acid and Bases 1 Determining Acids and Bases SNC-2D1 April 02‚ 2013 Acid and Bases 2 Purpose The purpose of this chemistry lab is to investigate and find patterns/tendencies between substances Introduction An acid is a solution that has more free hydrogen ions (H + ) than hydroxyl ions (OH - ) and a pH less than 7. A base is a solution that has less free hydrogen ions (H + ) than hydroxyl ions (OH - ) and a pH of more than 7. In the late 1800s‚ the Swedish scientist Svante

Many nurses are weak with drug calculations of all sorts. This article will help to review the major concepts related to drug calculations‚ help walk you through a few exercises‚ and provide a few exercises you can perform on your own to check your skills. There are many reference books available to review basic math skills‚ if you find that you have difficulty with even the basic conversion exercises.

CULINARY CALCULATIONS The Standardized Recipe The standardized recipe is the hallmark of the foodservice industry today. The information contained in the standardized recipe ensures that a consistent product is always served to the guest. A consistent product means the look‚ taste‚ texture‚ and portion size of the menu item is the same each time the item is prepared and served‚ regardless of who is in the kitchen on a given day. Each standardized recipe has a specific yield‚ which can be increased

POWER CALCULATION Power is the quantity work has to do with a force causing a displacement. It is the rate at which work is done. (http://www.physicsclassroom.com/class/energy/u5l1e.cfm) We can calculate power with using the following equation. In this experiment I calculated my power with Power (watt)=mass (kg) *gravitational acceleration (m/s2)*height(m)/time (s) I made the experiment with my controller for getting more reliable datas.I calculated my power with cliambing upstairs and
