Finding the Kinetic Energy of a particle in 2mol of nitrogen

AI Thread Summary
The discussion revolves around calculating the kinetic energy of a particle in 2 moles of nitrogen gas at atmospheric pressure within a volume of 100 m³. Participants express confusion about the relationship between kinetic energy, pressure, and volume, seeking clarity on the underlying principles, particularly ideal gas theory. Suggestions are made to review course materials and utilize resources like Hyperphysics for better understanding. After further attempts, one participant successfully arrives at answer A, though they encounter discrepancies with their calculator's output. The conversation emphasizes the importance of grasping kinetic temperature and its implications for gas behavior.

Homework Statement



What is the kinetic energy of a particle in 2mol of nitrogen gas at atmospheric pressure that is within a volume of 100m^3?a. 1.27X10^-17J
b. 3X10^5J
c. 6.8X10^-16J
d. 2.97X10^7
e. 9.9X10^-14J

Homework Equations



PV=nRT
n=Numberof particles/Na
Na=6.02x10^23
R=8.13 J/Mol

The Attempt at a Solution


[/B]
I know that atmospheric pressure is 1.013x10^5. The nitrogen part is what confuses me. I'm not sure where to start in solving this.

What does the kinetic energy of a particle in a gas depend on? Does it depend on the pressure? The volume? If not, then what?

I honestly don't know. I'm too frustrated to think straight at the moment. I am mad that I am not getting this.

Do you have a book or course notes you can review? Have you talked about ideal gas theory in class?

yes. we just learned this yesterday. i guess id have to look through the book. The teacher isn't very good. the class notes given are a bit confusing to understand
 
You may also find that Hyperphysics web site to be a great resource that succinctly summarizes specific topics.

Hint: Do a web search on Kinetic Temperature

Thanks. Ill check it out. I tried again and got A. But the powers came out different on my calculator.
