Let’s be real: the first thing you’ll do is type the compound’s name into a search bar. That’s smart! You’ll probably get a number like “100°C for water” or “78°C for ethanol.” But here’s the catch: that number is the boiling point at sea level (1 atmosphere of pressure). If you’re in Denver or at the top of a ski mountain, that number is a dirty liar.
Higher altitude = lower air pressure = molecules party harder and escape sooner. Water boils at 95°C in the mountains, not 100°C. So before you trust the internet, check your local weather report… or at least look at a barometer. The internet won’t know you moved to a cabin in the woods.
