Ideal Gas Law

Postby William Chan 1D » Sun Jan 12, 2020 6:28 pm

Under what conditions does the ideal gas law deviate and why? Do we need to memorize why?

The ideal gas law deviates because of two things usually. Primarily, intermolecular forces are always present and although very small/negligible in high heat, are increasingly important in lower temperatures. In addition, the fact that even as pressure continues to increase, the gas volume will never reach exactly zero.
Unfortunately, I'm sure if we have to memorize specific scenarios this occurs in or which those scenarios would be. Sorry that's not as helpful.

The ideal gas law is only valid when there is low pressure and high temperature.

You can only use pV=nRT if there is low pressure and high temperature.
