They called carbon dioxide, and oxygen and nitrogen, «ideal gases», and said they behave as per basic ideal gas description (pre Van der Waals), in other words, they have taken all the properties and process of real gases out of their «gases» and reduced them to hard dots with no mass, (no volume, weight or attraction and therefore nothing to be subject to gravity), and they say these travel at great speeds through empty space as per ideal gas, bouncing off each other in elastic collisions and so «thoroughly mixing» that they can't be unmixed (without an immense amount of work being done, so for all practical purposes can not be unmixed).
