Two bottles of water are used in an experiment. One bottle is heated and yellow food coloring is added to it. The other bottle is cooled and blue food coloring is added to it. The yellow bottle is placed on top of the blue bottle so that the liquids in each bottle can touch. After one minute, the liquid in the bottles appears as shown below. Explain why these liquids appear as shown. How this experimentation exemplifies heat transfer by convection. How would these bottles look after an hour?
