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

1. The partial molar volumes of acetone and chloroform are 74.16 cm3 mol-1 and 80.23 cm3 mol-1 respectively. Calculate the volume of a mixture containing 25.00 moles of acetone and 75.00 moles of chloroform. 2. Acetone has a molar mass of 58.1 g mol-1 and a density of 0.787 g cm-3. Chloroform has a molar mass of 119.4 g mol-1 and a density of 1.499 g cm-3. Estimate the volume of the above mixture using this information. 3. Calculate the molal freezing point depression constant Kf for

refluxing‚ extraction‚ and esterification. Firstly‚ esterification and refluxing‚ the acid and alcohol are first warmed and mixed together with the sulphuric acid catalyst then attached it to a reflux condenser for a period of time. Then extraction‚ chloroform was added in to the mixture as organic solvent‚ causing it to form 2 layers. The ester solution layer was then extracted and drying agent was added to remove water. Then the solution undergoes filtration. The last step is the distillation. This

One factor that Roald Dahl uses that contributes to his exclusive writing style is suspense. This element is used a lot in the story‚ “Poison‚” but one of the biggest scenes it shows up in is when Dr. Ganderbai injects the serum into Harry. “He held it up to the light‚ squinting at the calibrations‚ squirting out some of the yellow fluid. I stood still beside him‚ watching. Harry was watching too and sweating all over his face so it shone like it was smeared thick with face cream melting on his

the rest of the tea prior to evaporation. This process is known as an extraction. An Extraction is a chemical method of separating a specific component of a solution from the rest of the solution. This is done by using a solvent (in this case Chloroform) in which the substance to be isolated is very soluble‚ while the rest of the solution is not as soluble. For the purposes of this
