Question 171: Thermodynamics & KTG

Question

The specific heat at constant pressure of a real gas obeying $P V^2=R T$ equation is:

Accepted Answer

$\begin{aligned}
& \because \quad P V^2=R T \
& P(2 v d v)+V^2(d P)=R d T
\end{aligned}$
at $P=$ const.
$P d v=\frac{R d T}{2 V} \quad 	ext{... (i)}$
Now, for $n=1$
$\begin{aligned}
& d 	heta=d v+d w \
& C_P d T=C_v d T+P d v \quad 	ext{... (ii)}
\end{aligned}$
from (i) and (ii)
$C_P=C_V+\frac{R}{2 V}$

Answer

R

Answer

$C_V+R$

Answer

$C_V+\frac{R}{2 V}$

Answer

$\frac{R}{3}+C_V$
