Calculate charge in interanl energy for a gas under going from state-I `(300 K, xx 2 xx10^(-2) m^(3))` to state -II `(400 K, 4 xx 10^(-2) m^(3))` for one mol .of vanderwaal gas. `[C_(V)=121J//K//"mole"]` `{Given : ((delU)/(delV))_(T)=T((delP)/(delT))_(V)-P` `C_(V)=12 J//K//mol` `a=2 J .m.//mol^(2)}` |
| Answer» `DeltaU= C_(V)(T_(2)-T_(1))+a((1)/(V_(1))-(1)/(V_(2)))=C_(V)(100)+a((1)/(4))xx10^(2)=12xx100+2((1)/(4))xx100=125` | |
