摘要

Years ago, in some dank basement, a contractor installed a large air vent near the end of a steam main. He did this because he knew that steam and air are both gases, but steam is lighter than air, so the two won't mix. He also knew that the empty steam main was going to start out filled with air (which is only natural, right?), and that once it left the boiler, the steam would shove the air ahead of itself and down the main, just like a big, hot plunger.
