The definition of boiling in English states that it's a process
induced by adding heat. It says nothing about reducing pressure.

To claim you can make water boil by reducing pressure is erroneous.
(where's the application of heat?)

You can only vaporize water by reducing pressure. You can't boil
water by reducing pressure. Saying "I'm gonna boil this water
by reducing pressure" is like saying, "I'm gonna drink this beer
by putting it up my ass via enema." Just as the verb "to drink" means
to ingest via the mouth and esophagus so does the verb "to boil"
mean vaporize by adding heat.

And, your lack of understanding of a simple word definition and its
implications means you're lacking insight.
