Started a bit on the power point. Not exactly sure what is supposed to be on the power point, so its kinda weird, but thats OK.
Another difference between hot and cold water is that hot water evaporates faster. So the entire surface of hot water has steam pressure. Just an interesting note. Got it from here: http://en.allexperts.com/q/Physics-1358/Differences-hot-cold-water.htm.
