Question

The pressure exerted by an ideal gas on the walls of a container is

• A. $\left[\frac{1}{3}\right]^{r d}$ of kinetic energy per unit volume of a gas
• B. $\left[\frac{2}{3}\right]^{r d}$ of kinetic energy per unit volume of a gas
• C. $\left[\frac{3}{4}\right]^{t h \, }$ of kinetic energy per unit volume of a gas
• D. $\frac{3}{2}\times $ kinetic energy per unit volume of a gas

Answer 1

Answer: (B)

The pressure exerted by the gas on the walls of container is
$P=\frac{1}{3}\rho v^{2}=\frac{1}{3}\frac{m}{V}.v^{2}\times \frac{2}{2}=\frac{2}{3}\frac{K E}{V o l u m e}$
