Microscopic potential energy of a gas

AI Thread Summary
The discussion centers on the potential energy of a gas when compressed by a piston in a gas syringe. It is clarified that the work done by the piston increases the internal energy of the gas, which is often confused with potential energy. The conversation highlights that if no heat escapes, the internal energy increases, implying a rise in kinetic energy and temperature as well. The participants emphasize the distinction between potential energy and internal energy in thermodynamic processes. Overall, the interaction illustrates the relationship between work, energy, and temperature in gases under compression.

hello
In a textbook it is stated that if a piston of a gas syringe is used to compress the gas inside. Its Potential Energy increases. Can anyone give me a reason for this?

Also please give me a gross idea that on which factors does potential energy of a gas depends.

hello...
 
The piston is doing work on the gas, thus adding energy the system. If no heat (or other energy) escapes, the internal energy of the gas must increase. (Where you say potential energy, I think you mean internal energy.)

no i was only considering potential energy, disregarding the kinetic energy.
 
that link was helpful...but one last thing...
you say internal energy increases as a whole...does that mean Ek should also increase causing temp to rise as well?
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
