Question

Ideal gas assumptions exclude:

RankGuru · Accepted Answer

A central assumption of the **Ideal Gas** model is that the molecules are 'point masses'. 
- This means their **actual volume is negligible** (treated as zero) compared to the volume of the container.
- If the finite volume of molecules is considered (as in the van der Waals equation), the gas is no longer 'ideal'. 
- Other assumptions (point particles, elastic collisions, no long-range forces) are indeed parts of the ideal gas framework.
