Question

The ratio of specific heat at constant volume of one mole monoatomic gas to the one mole diatomic gas is given as \(\frac{a}{b}\) where a and b are co-prime number, then find (a+ b) 

Answer 1

Correct Answer is : 8 

\((C_v)_1= \frac{3}{2}R\) 

\((C_v)_2= \frac{5}{2}R\) 

\(\frac{(C_v)_1}{(C_v)_2}\) = \(\frac{3}{2}\times\frac{2}{5}\) = \(\frac{3}{5}\)
