    Distillation Andrea PausmaOctober 1, 2001 I. Introduction The process of distillation has been used by humans for years to create alcoholic beverages. Distillation is the process of boiling a pair of liquids with different boiling points and then condensing the vapors above the boiling liquid in an attempt to separate them. One might suspect that the mixed two liquids of different boiling points could be separated simply by raising the temperature to the lower boiling point of the two liquids. H...
  • Fahrenheit's Thermometers
    693 words
    Daniel Fahrenheit Daniel Fahrenheit was born in the Polish city of Gdansk on the 14th of May 1686. He was the oldest of five children and only fifteen when his parents both died. The city council put the four younger Fahrenheit children in foster homes. But Daniel Fahrenheit was instead to complete a four year apprenticeship in which he learnt about bookkeeping. After his four years were over he turned to physics and became a glassblower and instrument maker. In 1701, Fahrenheit spent ten years ...

    Determination of Melting Points of Benzoic Acid and Benzamide and Composition Diagram of Their Mixtures PURPOSE: The purpose of this experiment is to determine the melting point of benzoic acid and benzamide and make a composition diagram for the mixtures of benzoic acid and benzamide to determine the eutectic point of the mixtures. The melting point of the given unknown will be determined using the melting point apparatus. Pure chemicals such as benzoic acid and benzamide alone have a set melti...
  • Boiling Point For Cyclohexane The Distillate
    654 words
    INTRODUCTION: Simple distillation is a process to purify volatile compounds or compounds with different boiling points. It is a simple process that takes a mixture of compounds and applies heat. The substance with the lowest boiling point, (usually the most volatile), will boil and vaporize first. Using a distillation apparatus consisting of a flask, glass tubes, thermometer, condensing tube and distillate container, the first gaseous vapor that rises can be condensed back into liquid. This liqu...
  • Impurities The Melting Point
    543 words
    Regelation is the fusion of two blocks of ice by pressure, or the "successive melting under pressure and freezing when pressure is relaxed at the interface of two blocks of ice". It is a phenomenon in which water refreezes to ice after it has been melted by pressure at a temperature below the freezing point of water. This pressure makes an ice skate form a film of water that freezes once again after the skater has passed. The effect of impurities on melting point A substance containing impuritie...
