>>	Work from an Adiabatic Expansion Anonymous 08/06/03(Tue)01:12 No. 166 File: 121246995246.jpg-(117.95KB, 1184x622, adabiat77.jpg) Work from an Adiabatic Expansion

>>	An Expanding Monatomic Gas Anonymous 08/06/03(Tue)01:33 No. 167 An Expanding Monatomic Gas answer=123 (2000-1260)/n/(5R/3)=t=-10.68 135-10.68=124.31
