A student fills a large container with cold water. He fills another, smaller container with hot water and red food coloring, and seals it with a lid. Next, he places the small container of hot water into the larger container of cold water. When he removes the lid on the small container, he observes the colored water rising up to the top of the cold water. Why does this occur? Select all that apply.

wrong
I apologize for the error in my responses. The correct answers are:
- because the hot water is less dense than the cold water
- because the hot water molecules move faster than those of cold water
Thank you for pointing out the mistake.
