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

$10^{23}$ molecules of a gas, each having a mass of $3 \times 10^{-27} \,kg$, strike per second per $cm^2$ of a rigid wall at an angle of $60^{\circ}$ with the normal and rebound with a velocity of $500 \,m/s$. The pressure exerted by the gas molecules on the wall is: (in $\,N/m^2$)

The temperature of a gas is $-68^\circ C$. At what temperature in $^\circ C$ will the average kinetic energy of its molecules be twice that of at $-68^\circ C$?

The energy (in $eV$) possessed by a neon atom at $77^{\circ} C$ is (Boltzmann constant,$K_{B} = 1.38 \times 10^{-23} \,J \,K^{-1}$)

$Assertion$: The total translational kinetic energy of all the molecules of a given mass of an ideal gas is $1.5$ times the product of its pressure and its volume.
$Reason$: The molecules of a gas collide with each other and the velocities of the molecules change due to the collision.

If the average kinetic energy of a gas molecule at $27^{\circ} C$ is $3.3 \times 10^{-20} \,J$, then the average kinetic energy of the gas molecules at $127^{\circ} C$ is
