Question : 43 of 180

Marks: +1, -0

A cubic vessel (with faces horizontal + vertical) contains an ideal gas at NTP. The vessel is being carried by a rocket which is moving at a speed of 500ms−1 in vertical direction. The pressure of the gas inside the vessel as observed by us on the ground

Remains the same because 500 m/s is very much smaller than of the gas
Remains the same because motion of the vessel as a whole does not affect the relative motion of the gasmolecules and the walls
Will increase by a factor equal to (Vrms2+(500)2)/vrms2 where Vrmswas the original mean square velocity of the gas
Will be different on the top wall and bottom wall of the vessel
