"Hardness" is only defined for solids - not for liquids or gases.
hard
This exchange of gases does not depend how "hard" you breathe but operates on the principle of Diffusion
John Dalton is credited with proposing the theory that atoms were hard spheres based on his work with gases in 1808.
Attraction between the atoms increases
Hmm that's a hard one air .
It was dalton
1. Gases are hard spheres 2. Gases move in constant random motion that's all I know sorry ... :(
Your breath is a mixture of gases (including a combination of nitrogen, oxygen, carbon dioxide, and a few inert gases). ITS A GAS IT IS NOT LIQUID YOU DUBM @$$ NOT THAT HARD
The hard sphere model was introduced by physicist David Langmuir in the early 20th century. It is a simplification used in statistical mechanics and physical chemistry to describe the behavior of gases and liquids by modeling particles as hard, non-deformable spheres that collide elastically. This model helps in understanding the properties of gases and the interactions between particles in a simplified manner.
No, probably not because Saturn is made up of helium gases and you can't exactly have a gas land slide. The planet is entirely made up of gases except inside the planet it is rock hard.

Ability to assume the shape of its container Low density apexIt has no definite shape or volume.are the -thing which is hard to see
