ANSWER
K.C.S.E Physics Q & A - MODEL 2009PP1QN08Two identical empty metal containers P and Q are placed over identical Bunsen burners and the burners lit. P is dull black while Q is shiny bright. After each container attains a temperature of 1000C the burners are turned off. Identical test tubes containing water are suspended in each container without touching the sides as shown in figure 3
​Explain why the container Q may become hot faster than P.
Explain why the water in test- tube in P becomes hot faster than in Q

​Two identical beakers A and B containing equal volumes of water are placed on a bench. The Water in A is cold while in B it is warm. Identical pieces of potassium permanganate are placed gently at the bottom of each beaker inside the water. It is observed that the spread of colour in B is faster than in A. Explain this observation.
