• # question_answer 39) For hydrogen gas ${{C}_{p}}-{{C}_{v}}=a$ and for oxygen gas ${{C}_{p}}-{{C}_{v}}=b$. So, the relation between a and b is given by        A)  $a=16\,b$                  B)  $16\,a=b$C)  $a=4b$                      D)  $a=b$

Both are diatomic gases and ${{C}_{P}}-{{C}_{V}}=R$ tor all gases.
