For hydrogen cP - cV = n1 and for nitrogen cP – cV = n2 where cP and cV represents specific heat per unit mass respectively at constant pressure and constant volume respectively. The relation between n1 and n2 is
(Molecular weight of hydrogen = 2, and molecular weight of nitrogen = 14)
(1) n2 = 14 n1
(2) n2 = 7 n1
(3) n1 = 7 n2
(4) n1 = 14 n2
