How is the behavior of food coloring in the cool and heated water different? What caused the differences in their behavior?

Answer:

The food coloring in cool water remained at the bottom. In heated water, it rose to the top, moved to the sides, and then sank. The heated water was less dense and rose, while water cooled at the surface, became denser, and sank. This movement created convection currents.

Which of these ideas did you include in your answer? Check all that apply.

A
The food coloring in the cool water stayed at the bottom of the container.
B
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.
C
Warm water is less dense and rises and cold water is more dense and sinks. These differences cause convection currents.

B
The water carried the pieces of paper to the sides of the container.
C
The water pushed the pieces of paper to the top of the container.
D
The water pushed the pieces of paper to the bottom of the container.
