So that means we can use the kinetic theory to approximate how this behaves. Because if the distance is far then we can assume the volume of the molecules to be very, very small. And since they're far away, we can assume they don't attract or repel each other. However, when we get to this state what happens here at high temperatures? Suppose this is 1000 ATM and still zero Celsius. So our volume has decreased tremendously and our pressure has increased but temperature remains the same.
