The Effects of Water on the Environment

Dr Sophie is trying to come up with an answer for why water freezes on the inside of a pot when it's at 20 degrees C. But she needs physicists to ring in and help her out if they've got the right answer. It goes like this: molecules, H2O, which look like little boomerangs, are jiggling around so much that some reach temperatures corresponding to 100 degrees centigrade. They then break away into the air where they're hit entirely by cold air before condensing onto the side of the pot. As they condense, they go into a lower state of energy - keeping the outside warm. This means no frosting on the outside or cond
