Question

At a given temperature the pressure of an ideal of density $\rho$ is proportional to:

• A. ${\rho }^2$
• B.
• C. $\frac{1}{{\rho }^2}$
• D. $\frac{1}{\rho }$

Answer 1

Answer: (B)

$P=\frac{1}{3}\rho c^2\propto \rho$
Therefore at given temperature the pressure of an ideal gas is proportional to $\rho$.
