1. The problem statement, all variables and given/known data A gas of volume 1400[liter] and pressure 2.33[atm] expands in an adiabatic process to 2240[liter] and 1.2[atm]. plot the process on a V-P diagram. I shorten the question, only this interests me. the number of moles is given. 2. Relevant equations Equation of state: ##PV=nRT## 3. The attempt at a solution I calculated and drew the two states, see drawing. does the process go along a straight line, like the arrow, from one point to the other?
