Suppose the outer surface of the tumbler is greasy or has a film of cooking oil on it. Would it become easier or more difficult to hold it?

Text Solution

Verified by Experts

It would become more difficult to hold a glass tumbler with a film of cooking oil on its surface because this surface will provide no friction or least friction.

Hameed has built a cubical water tank with lid for his house, with each outer edge 1.5 m long. He gets the outer surface of the tank excluding the base, covered with square tiles of side 25 cm (see Fig. 13.5). Find how much he would spend for the tiles, if the cost of the tiles is ₹ 360 per dozen.

Emulsions are normally prepared by shaking the two components together vigorously although some kind of emulsifiying agent usually has to added to stabilize the product. This emulsifying agent amy be a soap or other sufactant (surface active) sepcies or a lyophilic sol that forms a protective film around the dispersed phase. Emulsion broadly classified into two types: (i) Oil in water emulsions (O/W): Oil acts as dispersed phase and water acts as dispersion medium. (ii). Water in oil emulsion (W/O): Water acts as dispersed phase and oil acts as dispersion medium Due test, dilution test may be emplyoyed for identification of emulsions. Q. Read two statment s: (1) milk is an example of oil in water (O/w) type emulsion (2) cold cream is an example of water in oil (W/O) type emulsion
