MCQ->If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical solution temperature (CST or consolute temperature). If solubilities increase with decrease in temperature, then CST is the temperature below which they dissolve completely. If a binary system has no critical solution temperature, it implies that....
MCQ->The simplest method of welding two pieces of metal together is known as pressure welding.The ends of a metal are heated to a white heat-for iron,the welding temperature should be about 1300C-in a flame.At this temperature the metal becomes plastic.The ends are pressed or hammered together,and the joint is smoothed off.Care must be taken to ensure that surfaces are thoroughly clean first,for dirt will weaken the weld.Moreover,the heating of iron or steel to a high temperature cause oxidation,and a film of oxide is added to the heated surfaces.For this reason,flux is applied to the heated metal.At welding heat,flux melts and the oxide particles are dissolved in it together with any other impurities which may be present.The metal surfaces are pressed together,and the flux is squeezed out from the center of the weld.A number of different types of weld may be used,but for fairly thick bars of metals,a vee-shaped belt should be normally employed.It is rather stronger than ordinary butt weld. The simplest way of welding two pieces of metal together is....
MCQ->Read the following passage carefully and choose the most appropriate answer to the question out of the four alternatives. In short, to write a good letter you must approach the job in the lightest and most casual way. You must be personal, not abstract. You must notsay, 'This is too small a thing to put down'. You must say, 'This is just the sort of small thing we talk about at home. If I tell them this they will see me, as it were they'll hear my voice, they'll know what I'm talking about'. That is the purpose of a letter. Carlyle had the trick to perfection. He is writing from Scotsbrig to his brother Alec in Canada and he begins talking about his mother. Good old Mother, he says, 'she is even now sitting at my back, trying at another table to write you a small word with her own hand the first time she has tried such a thing for a year past. It is Saturday night, after dark we are in the east room in a hard, dry evening with a bright fire to our two selves Jenny and her Barns are 'scouring up things' in the other end of the house and below stairs the winter operations of the farm go on, in a subdued tone you can conceive the scene!
