12.Kinetic Theory of Gases
normal
વિશિષ્ટ ઉષ્માઓનો ગુણોત્તર $\left(\frac{C_{P}}{C_{V}}\right)$ ને મુક્તતા અંશો $(f)$ ના પદમાં ...........રીતે લખી
A
$\left(1+\frac{f}{3}\right)$
B
$\left(1+\frac{2}{ f }\right)$
C
$\left(1+\frac{ f }{2}\right)$
D
$\left(1+\frac{1}{ f }\right)$
Solution
Molar heat capacity at constant volume $C _{ V }=\frac{ fR }{2}$ where $f$ is degree of freedom.
Molar heat capacity at constant pressure can be written as $C_{P}=R+C_{V}=R+\frac{f R}{2}=\left(1+\frac{f}{2}\right) R$
So $\frac{ C _{ P }}{ C _{ v }}=1+\frac{2}{ f }$
