Question

Which one of the following alcoholic drinks is produced without distillation ?

• A. Wine
• B. Whisky
• C. Rum
• D. Brandy

Answer 1

The Correct Option is A

Wine is the alcoholic drink produced without distillation whereas whisky, rum and brandy are produced by the distillation of the fermented broth. The alcoholic drinks are formed either by distillation or without distillation depending on the type of raw material used for fermentation.

Answer 2

Ans: The alcoholic beverages can be put into two categories:

• Fermented (non-distilled) beverages 
• Fermented  (distilled) beverages 

For, the process of distillation to produce alcohol. First the base alcohol needs to be made. By the process of distillation, the alcohols are separated from the water by both evaporation and condensation. For this first , the base alcohol is heated by further capturing some part of the alcohol, to concentrate it. This process of distillation is done in stills. There are two types of stills used, continuous and pot stills. There are three parts of still, the still( also known as retort) that  will heat the liquid, the condenser and the receiver.  

Whisky, Rum and Brandy are the alcohols that are formed by the process of distillation. On the other hand, wine is produced without distillation. Wine is produced by the fermentation process of grapes. 

Ques: The largest number of molecules is in: 

Ans: One mole of a substance is the amount of substance that has the same number of particles as the number of carbon atoms in 12g of C-12 carbon. In 1 mole of a substance there are 6.023 x 10²³ number of atoms. 

To calculate the number of molecules in a substance, find the molecular weight of the substance. This molecular weight will have the avogadro number of molecules. Now calculate the molecules for the given mass of the substance. 

In the question: 

1. 34g of H₂O

Molecular weight of H₂O is 18g 

18g of H₂O = 6.023 x 10²³ molecules 

Now, 34g of H₂O  = 6.023 x 10²³ x 34/18 

= 11.33 x 10²³ molecules 

1. 28 g of CO₂

Molecular weight of CO₂ is 44 g 

44 g of CO₂ =  6.023 x 10²³ molecules 

Now, 28g of CO₂ = 6.023 x 10²³ x 28/44

=3.8 x 10²³ molecules 

1. 46 g of ethyl alcohol 

Molecular weight of ethyl alcohol = 32g 

32 g of ethyl alcohol = 6.023 x 10²³ molecules 

Now, 46 g of ethyl alcohol  = 6.023 x 10²³ x 46/32

= 8.625 x10²³ molecules 

1. 56g of N₂O₅

Molecular weight of N₂O₅ = 108g 

108 g of N₂O₅ = 6.023 x 10²³ molecules 

Now, 56 g of N₂O₅ = 6.023 x 10²³ x 56/108

= 3 x 10²³ molecules 

Therefore, 34g of water has the highest number of molecules.
