Homework Statement
Calculate the work done by the system in an irreversible (single step) adiabatic expansion of 2 moles of a polyatomic gas ([itex]\gamma[/itex] = 4/3) from 300K and pressure 10 atm to 1 atm.
Homework Equations
Work done in adiabatic process
W = nCv[itex]\Delta[/itex]T
n = Moles of gas
Cv = R/([itex]\gamma[/itex]-1) R-Universal gas constant
[itex]\Delta[/itex]T- Change in absolute temperature
The Attempt at a Solution
The given answer is 405R. I am unable to find out the change in temperature as final temperature and volume are unknown. Is there any other formula to calculate the work done in adiabatic expansion?
