Hypothetically: vacuum and wind?
If I had a room, properly sealed, and sucked all the air out of it and put a fan (box fan or a desk fan whatever) in the middle and turned it on would there be a breeze? If I put my hand infront of the fan would I feel it? (Obviously I’d have some sort of breathing apparatus but that is besides the point)
and why?
If there was no mass of air in the room then you would not feel a breeze. What you feel with a breeze is the molecules of air hitting your skin.
