(whether these interactions are attractive or repulsive depends on the molecules in question.) assuming that the air molecules would attract each other at low temperature, they would then tend to pull each other away from the walls of the container more than an ideal gas. do you think this would result in a higher or lower pressure vs that predicted by the ideal gas law?
