You are telling me the vacuum pump makes it not an apparent external influence? It is kinda loud?

She wasn’t saying that water was spontaneously boiling in this chamber. She was saying that they were in a space-equivalent chamber with a pressure such that water would spontaneously boil. If you found yourself in the environment that is being simulated here (outer space), you would be able to observe water spontaneously boiling workout the vacuum pumps.

The act of going into space is very apparent. There is a giant rocket you are strapped to. My point isn’t arguing “spontaneous boiling”, which in this case is used correctly. But rather the common use of spontaneous in this thread is defined as having no apparent cause. That’s just not true. There is a cause, in the picture, the pressure of the room is being manipulated. And the reason for the water boiling is the ΔP.

Idk man, my ears are pretty good at estimating quick relative pressure changes.
Also, were I in a spavesuit, I’d probably have trouble judging temperature changed as well.
