This lab involves using thermodynamics to calculate the work done in specific processes and the use this to determine the change in internal energy or the heat transfer via the first law of thermodynamics (E = Q – W). First start with an isothermal expansion at 2.0 atm from 1.0 L to 4.0 L. If this now is adiabatically compressed back to its original volume, what is the change in internal energy here? Also what are some examples of these processes?


I work in the Army as a general construction engineer.
