સમોષ્મી પ્રક્રિયામાં દબાણ એ તાપમાનના ઘનના સપ્રમાણમાં હોય,તો $\frac{C_p}{C_v}= $

A

$1.5$

B

$1.33$

C

$2$

D

$1.67$

Solution

(a) Given $P \propto {T^3}$, but we know for an adiabatic process, the pressure $P \propto {T^{\gamma /\gamma – 1}}$

So $\frac{\gamma }{{\gamma – 1}} = 3 \Rightarrow \gamma = \frac{3}{2} \Rightarrow \frac{{{C_P}}}{{{C_V}}} = \frac{3}{2}$
