Homework Statement
[/B]
There is a lid on a .25m diameter, .30m tall cylindrical container enclosing .021kg of air. The lid is held in place solely by atmospheric pressure. It take 220N of force to pull of the lid at an atmospheric pressure of 101kPa. What is the Temperature of the enclosed gas.
Homework Equations
PV =nRT
The Attempt at a Solution
So got the volume of the container by doing .3m * pi * (.25m/2)^2 which is .0147m^3 than I got the density of the container doing (.021kg/.0147m^3) = 1.43kg/m^3
At this point I am lost I don't understand what to do with the 220N force on the lid or how to get the pressure of the inside of the container.
