Let's imagine you have a container that has a pressure of 10 Pascals inside and a vacuum outside. The container has a volume of a cubic meter and I'm not sure if the temperature matters but lets say it's 293.5k. A small hole with an area A of a square millimeter is punctured into the wall of the container. Would the pressure exerted by the escaping air be greater than 10 pascals initially or would it be 10 Pascals exactly? And how many Newtons would be there exerted on A? I'm guessing that the pressure is 10 N/m^2 but since the area is smaller than a meter squared then the force in Newtons must be larger? Or does the pressure stay the same but the Newtons become larger?

The force would be proportional to the area, so the force on the hole would be 10^(-5) N
