1.	Figure show plot of (PV)/(T) and P for 2gm of oxygen gas at two different temeratures. (i)The significance of dotted line (ii)The relation between T_(1) and T_(2) (iii)The value of (PV)/(T) where the curves meet on the Y-axis.
Answer» Solution :(i)For the DOTTED line ,`(PV)/(T)`=constat. It presents the behavior of an IDEAL gas. (ii)The gas equation PV =RT is true only at high temperature In figure ,curve for `T_(1)` is closer to the dotted line than curve for `T_(2)` Hence the relatioon between `T_(1)` and `T_(2)` is `T_(1)gtT_(2)` (iii)`(PV)/(T)=muR`.So the VALUE of `(PV)/(T)` where the curves meet on the Y-axis gives the value of `muR`. In this CASE`mu=(m)/(M)=(2)/(32)=(1)/(16)` `therefore(PV)/(T)=muR=(1)/(16)xx8.31=0.518`J/K
