Distillation is a process of separating the component substances from a liquid mixture by selective evaporation and condensation. Distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components of the mixture. In either case the process exploits differences in the volatility of mixture's components. In industrial chemistry, distillation is a unit operation of practically universal importance, but it is a physical separation process and not a chemical reaction.
Commercially, distillation has many applications. For example:
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.
Vassar College (/ˈvæsər/ VASS-ər) is a private, coeducational, liberal arts college in the town of Poughkeepsie, New York, in the United States. Founded as a women's college in 1861 by Matthew Vassar, the school is one of the Seven Sisters and has a historic relationship with Yale University; it became coeducational in 1969. The college offers B.A. degrees in more than 50 majors and features a flexible curriculum designed to promote a breadth of studies. Vassar also offers many extracurricular organizations including student theater, a cappella groups, club sports, volunteer and service groups, and a circus troupe. Vassar College's varsity sports teams, known as the Brewers, play in the NCAA's Division III as members of the Liberty League.
Vassar tied for the 12th best liberal arts college in the nation in the 2016 annual ranking of U.S. News & World Report, with an admission criteria as "most selective." As of 2015, the college had an acceptance rate of 25.7%. The total number of students attending the college is around 2,450.
You will learn about "Simple Distillation" in this video. The process of heating a liquid mixture to form vapor and then cooling that vapor to get a liquid is called simple distillation. Distillation is used to purify a liquid by separating the components of a liquid mixture. Activity to understand Simple Distillation. Take a mixture of acetone and water in a distillation flask. Put a thermometer in it. Connect the flask to a water condenser. The condenser has cold water running through its jacket to keep the temperature cool. Keep a beaker at the outlet of the condenser. Heat the mixture, keeping an eye on the thermometer. When temperature hits 56 degrees celsius, acetone starts to vaporize. These vapors condense in the water condenser. The condensed acetone gets collected in the beaker. ...

Distillation is a unit operation, or a physical separation process, and not a chemical reaction. Commercially, distillation has a number of applications. It is used to separate crude oil into more fractions for specific uses such as transport, power generation and heating. Water is distilled to remove impurities, such as salt from seawater. Air is distilled to separate its components—notably oxygen, nitrogen, and argon—for industrial use. Distillation of fermented solutions has been used since ancient times to produce di...

A History of the Art of Distillation - Whisky Documentary Whisky or whiskey is a type of distilled alcoholic beverage made from fermented grain mash. Various grains (which may be malted) are used for different varieties, including barley, corn (maize), rye, and wheat. Whisky is typically aged in wooden casks, generally made of charred white oak. Whisky is a strictly regulated spirit worldwide with many classes and types. The typical unifying characteristics of the different classes and types are the fermentation of grains, distillation, and aging in wooden barrels.

Περιγραφή
Caught me off guard with a fraudulent smile
Threw me in the back and took my things
So mysterious that I can't see
The loneliest behavior you couldn't comprehend
Call it all off and take me back home
Someone switched off the light again
Above it
Below it
Behind it
Dripping up and down
Your halls again
Having trouble breathing
Without your apparatus
I thought you'd stay with me
In the end
Straight back down
Or way back up
It's never any fun
When you know the end
Wrapped my head around a spring of logic
To find it's all fake and art is pretend
Call it all off and take me back home
Someone switched off the light again
You sleep to dream
(sleep to dream)
Your world without war and your rock stars
Your perfect house and your perfect car
You sleep to dream
While I dream of sleep
(dreaming to sleep)
Of which I cannot find
So I step inside
the sapphire bottle
to deliver the mind
down to the bottom I go
shot by shot
my dreams arrive
and this is all over now
I sleep long at last
and this is all over now
thanks to this bottle
It's all over now
You dream to sleep but it's all over now
It's over now
This song is pretty damn long
and you know you love it
we've been dreams from gin
It's over now
