The process is described by:

PV³=const

Hence it is a polytropic process.

as in polytropic process:

PVᵃ=const

C=Cv+R/(1-a)=3R/2+R/(-2)=R

C=R

Answer:

a).r

Explanation:

given that

p {v}^{3}  = constant \:  \:  \:  \:  (1)

we \: know \: that \: for \: polytrophic \:  \\ p {v}^{n}  = constant \\ implies \: that \: c = cv +  \frac{r}{(1 - 3)}  \\ \: so \: from  \: (1) \: we \:have \:   n = 3  \\  \\ then \\ c = cv +  \frac{3r}{2}  +  \frac{r}{2}  \\ that \: is \: c =  \frac{3r - r}{2}  \\ so\\c = r \\ therefore \: (a) \: is \: correct.
