1.	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 500 ms^(-1) in vertical direction. The pressure of the gas inside the vessel as observed by us on the ground
Answer» Remains the same because `500ms^(-1)` is very much smaller than `upsilon_(RMS)` 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 `[upsilon)(rms)^(2) + (500)^(2)[//upsilon_(rms)^(2)` where `upsilon_(rms)` was the original nean SQUARE velocity of the gas. will be different on the top wall and bottom wall of the vessel. SOLUTION :The pressure of the gas inside the vessel, as OBSERVED by us, on the ground remains the same. This is because motion of the vessel as a whole does not affect the relative motion of gas molecules and the walls of the vessel.
