Question
Suppose you accidentally stop your reaction too early or late so that the level of the liquid inside the hydrogen tube is 1.0 cm higher or lower than the water level in the tank. By what percentage will the gas pressure inside the tube be different from atmospheric pressure? (Hint: The pressure at depth h in a liquid of density (P) equals atmospheric pressure plus Pgh. Recall that the density of water is 1.0 g/cm^3 = 1000 kg/m^3.) This is very nearly equal to the percent error that this will contribute to the experimental value of ( e ) . You should find a small answer, indicating that it doesn
Explanation / Answer
percentage change in preesure=(change in pressure /original pressure)*100
% change in pressure =(Pgh/atmospheric pressure)*100=0.0961
