**Pressure and Volume work**
Hi everyone! This is my first post, so if you have tips on formatting please let me know.
I am currently in a graduate level dynamics class and right now we are studying the first law of thermodynamics.
The question that is giving me trouble is as follows:
One day the atmosphere to compresses one mole of Neon gas from a volume of 30 L to a volume of 4 L. Further, the temperature is maintained
at 280 K. So how much work does the atmosphere do?
SO - my first attempt: I calculated the Pressure of the air parcel by using the ideal gas law of PV = nRT. And then I think we can use pressure and change in volume to calculate work, but I am maybe missing the conceptual idea behind it.
The equation that I know is the integral of W from i to f = pdV - I don't get the integral part. do we have to integrate the values of pressure and the change in volume? This is what is tripping me up. Any tips are appreciated!!
