In an experiment to, a drop of black ink is introduced at the bottom of a container filled with water. It is observed that the water gradually turns black. State the effect on the observation when the experiment is carried out using water at a lower temperature.                                                                                                                             (1 mark)

In a physics experiment, a student filled a burette with water up to a level of 15ml. The student ran out 3 drops of water each of volume 2cm3

 from the burette into a beaker. Determine the final reading of the burette.                                                                                                                                                                                               (2 marks)

Three islands P,Q,R and S are on an ocean such that island Q is 400Km on a bearing of 0300  from island P. island R is 520Km and a bearing of 1200  from island Q. A port S is sighted 750Km due South of island Q.

(a) Taking a scale of 1cm to represent 100Km, give a scale drawing showing the relative positions of P,Q,R and S.     (4mks)
