Go to a dictionary and look up the definition of boil.
You will note that it mentions application of heat.

OK:

From my Funk and Wagnalls:

boil v.i. 1. To be agitated by escaping gaseous bubbles, usually from
the effect of heat: said of liquids.

Clearly the application of heat is not necessary.

I'm sure you have heard of people involved in high altitude research
talking of the possibility of having ones blood boil if exposed to near
vacuum. You appear to be engaging in an act of sophistry.
