Question

What are the conditions under which gases deviate from ideality?

Answer 1

Hi there,

The conditions under which gases deviate from ideal behaviour are;

1. Low Temperature
2. High Pressure

Low temperature and high pressure causes the volume of gasses to shrink. Due to this, they were occupying originally is now more than the volume. This causes the molecules to move from their original position and hence deviate from ideal behavior.

I hope the answer was satisfactory.

Thank you for asking.  

Answer 2

Real gases deviate from ideal behaviour because their particles(atoms for inert gases or molecules) occupy some finite space and do exert interactive forces among them. ... In ideal behaviour gasparticles don't occupy space and do not have any interaction, as assumed in kinetic theory of gases.


I think it will help you to deal with the chemistry....
