The boiling temperature of a liquid removes as much heat as is needed to maintain the boiling temperature of that liquid. Nobody can take any liquid to a temperature above that liquid's boiling temperature, right? If they could maybe they would find the boiling temperature of a portion of the original liquid, say a group of molecules, turning that group of molecules into a gas or vapor, while another portion of the original liquid remains in a liquid form. Now lets say the gas or vapor now has a void in the original molecular structure, of the original liquid. The gas or vapor has retained the most molecules. Because gas or vapor and liquid cannot occupy the same space, they seperated, due to their boiling temperature differences. When this happens air surrounding this process allows oxygen to fill this void in the gas or vapor and this invisible vapor turns white, in color. Now lets say the liquid retained is now non flammable and both were made from gasoline. Oh and the boiling temperature of the liquid is much higher than that of gasoline. Also at the temperatures the white gas appears, gasoline would be in a liquid form. Remember what can be done to one liquid can be done to any liquid. I did this to gasoline. See it on You Tube, White Gasoline Vapor. Read everything including the comments.
