| Sep 5, 2020 at 14:36 | comment | added | GiorgioP-DoomsdayClockIsAt-90 | @Buraian I wrote the reasin his presentation is misleading: he did not stressed that the validity of what he writes is depending on temperature too. The real reason is purely experimental (physics is not math!). However if you like to have a good theoretical argument, it is enough to take into account that within Statistical Mechanics, the ideal gas law can be obtained in the limit where Classical Mechanics is a good approximation of Quantum Mechanics and the kinetic energy is the dominant term in the Hamiltonian. Both conditions require high temperature. | |

| Sep 5, 2020 at 14:29 | comment | added | Brian | Why is he wrong and what you're saying is right? Sure, experimental results is one thing but for what intuitive reason should we expect this to happen. I mean to ask, is there any model which describes the intuition of this? | |
