What is the thermal energy of the gas?

AI Thread Summary
The discussion focuses on calculating the thermal energy of nitrogen gas in a cylinder with specific dimensions and conditions. The relevant equation for the thermal energy of a diatomic gas is not explicitly provided, prompting a request for clarification on its application. The pressure of the gas is noted to be 3500 Pa, which may be relevant for further calculations. The temperature of the gas is given as 20 degrees Celsius, and the rms molecular speed is 550 m/s. The conversation emphasizes the importance of using the correct formulas and parameters to solve for thermal energy.

Homework Statement



A 6.0-cm-diameter cylinder of nitrogen gas has a 4.0-cm-thick movable copper piston. The cylinder is oriented vertically,
and the air above the piston is evacuated. When the gas temperature is 20 deg C, the piston floats 20 cm above the bottom of the cylinder.
-If the rms molecular speed is 550 m/s, what is the thermal energy of the gas?

P was figured to be 3500 Pa

Welcome to PF :smile:

We generally like to see the sections from the homework template filled in. For example, what equation is there that deals with the thermal energy of a diatomic gas such as nitrogen?

Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
