If the gas inside the flask in the above exercise is cooled so that its pressure is reduced to a value of 715.7 torr, what will
1 answer:
Answer:
(a) 49.0 mm
Explanation:
#First we need to calculate the height of the mercury arm:
Reduced pressure is 715.7torr, Initial Pressure is 797.3torr, Required pressure is:
The difference in the two arms will give the pressure difference between the gas placed in the flask attached to an open-end mercury manometer.
Hence the height of the mercury in the arm is 49.00mm
