PLEASE HURRY IT'S URGENT Students in a science class performed an experiment with hot and cold water. They dyed the hot water red and the cold water blue. When the students mixed the water together, they noticed that the hot water rose to the top and the cold water sank. Eventually all the colored water mixed together. What kind of heat transfer did they observe happening?
