We can just produce atmospheric steam so it’s a simple phase change calculation.
Yes. Just assume the steam quality is as low as it gets. Use the lowest value from a steam table. The only thing you need to do is use a tall spout, like a tea kettle. This keeps drops of boiling water from spurting out. Some skeptics doubted that, but I pointed out you can test that easily by putting a Kleenex in front of a boiling tea kettle. It stays dry. Also, I asked them: Why do you think people have been making tea kettles and chemical retorts in that shape for thousands of years?
