thermodynamics - Why must the particles of an ideal gas be point-like?



Why is a gas of elastically colliding hard balls of finite size not ideal?



Respectively:



Why is it essential that the particles of an ideal gas are point-like?



Especially:




Which differing thermodynamic properties of a gas of not point-like particles are most striking in comparison with an ideal gas (of point-like particles)?

Understanding Stagnation point in pitot fluid

What is stagnation point in fluid mechanics. At the open end of the pitot tube the velocity of the fluid becomes zero.But that should result...
