Question

1. If we were to cool the air way down,the molecules would move more slowly, allowing them to come closer together where they would interact with each other. (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?

Explanation / Answer

As the molecules attract each other at low temperature , these will strike the wall with a lower force , which results in lower pressure.

Now ,according to idea gas law,

PV = nRT
Which also means , Pressure decreases with decrease in Temperature.

therefore , both this concept and ideal gas law predict the same, pressure will be lower
