The difference between the outer and inner curved surface areas of a hollow right circular cylinder 14 cm long is 88 cm^(2) . If the volume of metal used in making the cylinder is 176cm^(3) , find the inner and outer diameters.

The boiling point elevation and freezing point depression of solutions have a number of partical applications. Ethylene glycol (CH_(2)OH-CH_(2)OH) is used in automobile radiatiors as an antifreeze because it lowers the freezing point of the coolant. The same substance also helps to prevent the radiator coolant from boiling away by elevating the boiling point. Ethylene glycol has low vapour pressure. We can also use glycerol as an antifreeze. In order for the boiling point elevation to occur, the solute must be non-volatile, but no such restriction applies to freezing point depression. For example, methanol (CH_(3)OH) , a fairly volatile liquid that boils only at 65^(@)C , is sometimes used as an antifreeze in automobile radiators. If the cost of glycerol, glycol, and methanol is same, then the sequence of economy to use these compounds as antifreeze will be

A compound X is formed by the reaction of a carboxylic acid C_2H_4O_2 and an alcohol in the presence of a few drops of sulphuric acid. The alcohol on oxidation with alkaline potassium permanganate followed by acidification gives the same carboxylic acid as used in this reaction. Give the names and structures of the a) carboxylic acid b alcohol and c) the compound X. Also write the reaction.
