K.C.S.E Physics Q & A - MODEL 2018PP1QN17

​ (a) State Pascal’s principle of transmission of pressure in liquids. 
(b) Figure 10 shows heights of two immiscible liquids X and Y in a U-tube (drawn to scale).

​(i) State with a reason which of the two liquids X and Y has a higher density.
(ii) Determine the value of h. 
(iii) Given that the density of liquid Y is p, write down an expression for the density d of liquid X ¡n terms of p. 
(c) (i) With the aid of a diagram, describe how a liquid may be siphoned from one container to another using a flexible tube. 
(ii) State one application of the siphon.

answers

 (a) Pressure applied at one part in a liquid is transmitted equally to all other parts of the enclosed liquid.
