I know how suction cups work (or I think I do):
You push on the suction cup, pushing all the air out, which creates a low pressure. The cup is held in place because of the higher pressure of the atmosphere is pushing against the cup.
What gas law would this be?
Best Answer
This does not happen as a result of any gas law. It happens because there is a surprisingly high force from the atmosphere pressing down on the suction cups, and comparatively little force pressing up from the table and partial vacuum below.
