Possible Points: 3.33
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.
Which of the following ways could the experiment be continued to best illustrate the effects of convection?
Responses
Flip the water bottles upside down so that the blue bottle is on the top and the yellow bottle is on the bottom.

Pour the water from both bottles into a bowl and use a spoon to stir them together.

Unstack the bottles and measure the temperature of the yellow bottle and the blue bottle separately.

To best illustrate the effects of convection, the most suitable option would be:
**Flip the water bottles upside down so that the blue bottle is on the top and the yellow bottle is on the bottom.**
This method allows for the heated yellow water (which is less dense) to rise and interact with the cooler blue water (which is more dense). This demonstrates convection currents, as you would be able to observe how the warm liquid rises and the cool liquid sinks, effectively showcasing the principle of convection in a visible way.
The other options either do not effectively demonstrate convection (stirring the liquids would mix them immediately rather than allowing convection currents to form) or focus more on temperature measurement rather than the dynamic behavior of the liquids.
