Joshua fills one large container with cold water Then he fills a small container with hot water and red food coloring, and seals it with a lid. Next, he puts the small container into the large container and removes the lid of the small container. He observes the red colored water from the small container rising up to the top of the cold water. Which two statements explain why this happens?(1 point)

GPT-4o mini · Answer

The two statements that explain why the red colored water from the small container rises to the top of the cold water are:

because the hot water is less dense than the cold water
because the hot water molecules move faster than those of cold water

The hot water is less dense, which causes it to rise to the surface, and the faster-moving molecules of hot water help it to occupy space and rise through the cooler, denser water.
