Question 229: 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

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