Question 237: Thermodynamics & KTG

Question

P-T diagram of an ideal gas having three different densities $$\rho_1, \rho_2, \rho_3$$ (in three different cases) is shown in the figure. Which of the following is correct :

Accepted Answer

$$\begin{aligned}
& P M=ho R T \
& \Rightarrow \frac{P}{T}=\left(\frac{R}{m}ight) ho=	ext { slope }
\end{aligned}$$
So from given curve, $$ho_1>ho_2>ho_3$$

Answer

$$\rho_1>\rho_2$$

Answer

$$\rho_2<\rho_3$$

Answer

$$\rho_1=\rho_2=\rho_3$$

Answer

$$\rho_1<\rho_2$$
