“eau de vie” in French and “aqua vitae” in Latin. Definition • Distillation is the process of converting a liquid into gas or vapor by heating it and then condensing it back into liquid form. • When spirits are distilled the original liquid has already been fermented and is an alcoholic ‘wine’ or wash. After the ‘wine’ or wash has been converted into vapor and then condensed back into a liquid it is called a distillate. Impurities are left behind in the original container. • The equipment

liquids. Many organic compounds are volatile; that is‚ they have relatively high vapor pressures and low boiling points. The difference in how easily they vaporize is used to separate the chemicals from a mixture. As the mixture is heated‚ the temperature rises until it reaches the temperature of the lowest boiling point substance in the mixture‚ while the other components remain in its original phase. The resultant vapor will pass into the condenser and is converted to liquid. The other components

acetaldehyde by dehydrogenation of ethanol. Flow chart is as shown in the figure. Reaction: C2H5OH Catalyst: Æ CH3CHO + H2 Cu -Co-Cr2o3 Temperature: 280 – 3500 C. Process description: The raw material i.e.‚ ethanol is vaporized and the vapors‚ so generated‚ are heated in a heat exchanger to the reaction temperature by hot product stream. The product stream is cooled to –100 C and in doing it‚ all unreacted ethanol and acetaldehyde are condensed. The out going gaseous stream‚ containing

counterparts. The combination of THC and other compounds differs between smoke and vapor. CBD has a higher boiling point than THC. It is present in smoke but absent in vapor that is produced at lower temperatures. Vapor does not contain toxins like benzene and carbon monoxide that cause drowsiness. The amount of vapor is also less when compared to the amount of smoke released during the combustion of pot. When vaping‚ 95% of the vapor consists of CBD. 88% of smoke from combusted weed contains non-CBDs. Vaped

the dissolved particles and the solvent. Colligative properties are properties that depend on the dissolved solutes in the solution. There are four main colligative properties; vapor pressure‚ freezing point‚ boiling point‚ and osmotic pressure. These four colligative properties can be changed by using different solutes. Vapor pressure is lowered when solutes are added‚ the boiling point is elevated when solutes are added‚ the freezing point is lowered when solutes are added and the osmotic pressure

increased temperature there would be more cloud as our text states warm air can hold more water vapor than cool air. At a decrease temperature‚ it would be the opposite with less clouds and holding less water vapors. Experiment 1: Water Movement POST LAB QUESTIONS 1.

Vapor state (Sublimation) This can be observed in the process of evaporation that clouds are made of pure distilled water and that’s why rain water is so pure. Moreover the process of distillation can be performed in a laboratory. All elements have a property known as vapor pressure. The vapor pressure is a critical concept in the process of distillation. The more volatile a substance is‚ the greater its vapor pressure is. When vapor pressure of a substance meets
