Homework Statement
A perfectly fitting pot and its lid often stick after
cooking, and it becomes very difficult to open the lid when
the pot cools down. Explain why this happens and what you
would do to open the lid.
The Attempt at a Solution
I have no idea why. All I know is that atmospheric pressure is applied to the lid and that the vapor inside the pot applies pressure against atmospheric pressure. Also, I have a question: is the vapor subject to atmospheric pressure? I am thinking that since the lid fits perfectly with the pot, the atmospheric pressure is only applied to the lid and not the vapor.
Can anyone help me?
Thank you very much
