produces at least two output fractions. These fractions include at least one volatile distillate fraction‚ which has boiled and been separately captured as a vapor condensed to a liquid‚ and practically always a bottoms (or residuum) fraction‚ which is the least volatile residue that has not been separately captured as a condensed vapor. An alternative to continuous distillation is batch distillation‚ where the mixture is added to the unit at the start of the distillation‚ distillate fractions

separating mixtures based on differences in the conditions required to change the phase of components of the mixture. The product obtained by distillation is called the distillate. Volatility is the property of changing readily from a solid or liquid to a vapor. There are two types of distillation‚ simple and fractional. Distillation happens when a substance is heated and the more volatile compound starts to vaporize first. Those liquids having different boiling points are being separated here in distillation

2. Write a speech to persuade the Old Vic theatre to put on ’Othello’ giving reasons why it is an effective piece of drama. Use the film version as your source. William Shakespeare‚ England’s greatest writer. How could any Theatre deny this legend from their stage? His famous play Othello is a classic‚ a Greek tragedy promoting many themes‚ to name a few: love‚ anti – femininity‚ and racism. First performed in 1604 this intriguing storyline based in Venice and Cyprus has been thrilling audiences

by a simple distillation in which the material is placed to distill and heated‚ the vapor from the substance is removed and condensed. In this activity‚ we tend to separate ethanol with water. Simple distillation is employed in this process. Keywords: Distillation‚ Simple distillation‚ vaporization‚ volatile and nonvolatile materials INTRODUCTION Dissolved materials in a liquid may make it and its vapor passes through a condenser unsuitable for a particular purpose.

FACTORS AFFECTING SOLUBILITY There are three main factors that control solubility of a solute. (1) Temperature (2) Nature of solute or solvent (3) Pressure EFFECT OF TEMPERATURE Generally in many cases solubility increases with the rise in temperature and decreases with the fall of temperature but it is not necessary in all cases. However we must follow two behaviours: In endothermic process‚ solubility increases with the increase in temperature and vice versa. For

heat exchange processes. In this study‚ semi-empirical models are developed for design and rating of steam jet ejectors. The model gives the entrainment ratio as a function of the expansion ratio and the pressures of the entrained vapor‚ motive steam and compressed vapor. Also‚ correlations are developed for the motive steam pressure at the nozzle exit as a function of the evaporator and condenser pressures and the area ratios as a function of the entrainment ratio and the stream pressures.

supply.It can be solid (ice)‚a liquid (water)‚ or gas (water vapor). Water on earth is always changing. How do these changes happen? It is made up of a few main parts:evaporation (and transpiration)‚condensation and precipitation. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into the vapor. The water vapor leaves the river‚lake or ocean and goes into the air. Condensation is water vapor in the air gets cold and changes back into liquid‚ forming

Early in his address‚ Mandela proposes‚ “To my compatriots‚ I have no hesitation in saying that each one of us is as intimately attached to the soil of this beautiful country as are the famous jacaranda trees of Pretoria and the mimosa tress of the bushveld.”(¶ 05) By referring to the earth‚ Mandela reminds South Africans that all people are created equal and deserve happiness and prosperity. His word ‘equality’ is very effective because before his presidential term‚ Mandela was
