A cubic vessel (with faces horizontal + vertical) contains an ideal gas at normal temperature and pressure. The vessel is being carried by a rocket which is moving at a speed of 500 ms−1 in vertical direction. The pressure of the gas inside the vessel is observed by us on the ground:
- remains the same because 500 ms−1 is very much smaller than vrms of the gas.
- remains the same because motion of the vessel as a whole does not affect the relative motion of the gas molecules and the walls.
- will increase by a factor equal to\(\left[v_{\mathrm{mus}}^{2}+(500)^{2}\right] / v_{\mathrm{mus}}^{2}\) where \(v_{\text {ms }}\) was the original mean square velocity of the gas.
- will be different on the top wall and bottom wall of the vessel.
Answer
(B) remains the same because motion of the vessel as a whole does not affect the relative motion of the gas molecules and the walls.
