The pressure on the inside of the other side of the bottle is; 130kPa and this is by virtue of Pascal's Principle.
<h3>Pressure and Pascal's Principle</h3>
According to Pascal’s principle, otherwise called Pascal’s law, in fluid (gas or liquid) mechanics, the statement goes thus, In a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container in which the fluid is contained.
On this note, it follows that the pressure is transmitted to the walls of the bottle.
