Question

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.
c)it finally sank to the bottom. warm water is less dense and rises and cold water is more dense and sinks.
d)these differences cause convection currents.

Answer 1

In this experiment, the food coloring in the cool water stayed at the bottom of the container, while in the heated water, it first moved to the top and then spread to the sides before sinking to the bottom due to differences in density. These differences in density cause convection currents.

Step-by-step explanation:

In this experiment, we observed the movement of food coloring in both cool and heated water. In the cool water, the food coloring stayed at the bottom of the container, so option a) is correct. In the heated water, the food coloring first moved to the top of the container and then spread to the sides. Eventually, it sank to the bottom, which is due to the fact that warm water is less dense and rises, while cold water is more dense and sinks. So option b) and option c) are also correct. The differences in density between warm and cold water create convection currents, leading to the movement of the food coloring, so option d) is correct as well.
