Vedclass · Answer

(D) The volume of the cylinder is $V = 20 \, L = 20 	imes 10^{-3} \, m^3$.The total translational kinetic energy $E$ of an ideal gas is given by the formula $E = \frac{3}{2} PV$,where $P$ is the pressure and $V$ is the volume.Given $E = 1.5 	imes 10^5 \, J$ and $V = 20 	imes 10^{-3} \, m^3$.Rearranging the formula to solve for pressure $P$:$P = \frac{2E}{3V}$Substituting the values:$P = \frac{2 	imes (1.5 	imes 10^5)}{3 	imes (20 	imes 10^{-3})}$$P = \frac{3 	imes 10^5}{60 	imes 10^{-3}}$$P = \frac{3 	imes 10^5}{6 	imes 10^{-2}}$$P = 0.5 	imes 10^7 = 5 	imes 10^6 \, N/m^2$.

$A$ cylinder of capacity $20 \, L$ is filled with $H_2$ gas. The total average translational kinetic energy of the molecules is $1.5 \times 10^5 \, J$. Find the pressure of hydrogen in the cylinder.
