physical chemistry - Equations describing the liquifaction of gases


I would like to find out how much energy is required to liquify gases (oxygen or nitrogen, for example). What are some relevant equations?


I'm curious whether creating small quantities of dry ice or cryogenic fluids is feasible at home. If James Dewar was able to liquify hydrogen in 1898 surely it must not be that difficult!
