Vedclass · Answer

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

$A$ cylinder of capacity $20 \text{ litres}$ is filled with $H_2$ gas. The total average kinetic energy of translatory motion of its molecules is $1.5 \times 10^5 \text{ J}$. The pressure of hydrogen in the cylinder is
