Gentlemen, Thank you for time spent answering my question. Mark

If the 'test' sample was a theoretical column of air of a certain height and within that column were various strata of cold and hot air then wouldn't the two 'separate' conditions of hot and cold be then forced to interact and one strata to 'win out' over the other (move up or down)? Or am I insisting on making this more complicated than it is? Mark

Hot air rises due largely to fewer molecules = lighter = rising. Cold air sinks since more molecules = heavier = sinking. Fine. But that regards the two conditions as separate instances. In reality hot and cold air are both present. My question: Isn't a certain amount of hot air 'pushed' up by sinking cold air? Mark
