1.	During an isobaric heating process the work done by oxygen gas is 4 J. Calculate the amount of heat transferred to the gas. [gamma = 1.4]
Answer» Solution :HEAT transferred `= Q = ?` `Q = DELTA U + Delta W , Delta W = 4 J` `Delta U = n C _(V )Delta T = (n R Delta T )/( gamma -1) = (P Delta V )/( gamma -1) = (Delta W)/( gamma -1)` `Q = (Delta W)/(gamma -1)+ Delta W = Delta W [ (1+ gamma -1 )/( gamma -1) ] = (4 xx 1.4)/(1. 4 -1) =1.4 J`
