🤓 Based on our data, we think this question is relevant for Professor Williams' class at GS.
Recall that when the height of the gas in an open end arm is higher compared to the one next to the gas:
Pinitial = Patm + height difference (Pgas = Pinitial)
If the gas inside the flask is cooled so that its pressure is reduced from 797.3 torr to a value of 715.7 torr what will be the height of the mercury in the open-end arm? (Hint: The sum of the heights in both arms must remain constant regardless of the change in pressure.)
