    Gas Kelvin Zero
AI Thread Summary
An ideal gas can undergo adiabatic expansion, losing energy and decreasing in temperature without heat exchange. As the temperature approaches near zero Kelvin, gas molecules become increasingly spaced apart. Despite this, gases can remain in a gaseous state at very low temperatures, as evidenced by helium's triple point at approximately 2.2 K. This indicates that certain gases can maintain their gaseous state even at near absolute zero. Understanding these principles is crucial in the study of thermodynamics and low-temperature physics.

Consider an adiabatic expansion of an ideal gas that work is done against friction or a piston. Since no heat exchange can occur the gas keep on losing energy and its temperature decreases and the gas molecules getting further and further apart. In principle the temperature can get down to a few degrees Kelvin, close to zero K.

Is it possible that a gas can still be a gas at such a low temperature?

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
