Question

The food coloring in cool water remained at the bottom of the container. The food coloring in the heated water rose to the top and then moved to the sides of the container. It then sank to the bottom of the container. The behavior of the food coloring was caused by the movement of heat through the water and the formation of convection currents. Which of these ideas did you include in your answer? Check all that apply.

1) The food coloring in the cool water stayed at the bottom of the container.
2) The food coloring in the heated water moved to the top of the container then it moved to the sides of the container. It finally sank to the bottom.
3) Warm water is less dense and rises and cold water is more dense and sinks. These differences cause convection currents.

Answer 1

The behavior of food coloring in cool and heated water is caused by the process of convection and differences in density due to temperature variations.

Step-by-step explanation:

The behavior of the food coloring in the cool and heated water can be explained by the process of convection and the difference in density caused by temperature variations.

In the cool water, the food coloring remains at the bottom because cool water is denser and sinks. In the heated water, the food coloring rises to the top initially as the heated water expands and becomes less dense. It then moves to the sides of the container due to the formation of convection currents, where the hotter, less dense water rises and the cooler, denser water sinks.

These differences in density and the movement of heat through the water create a cycle of rising and sinking currents, known as convection. This process keeps repeating, allowing the food coloring to move throughout the container.
