2.) In a cylinder of cross section 1 dm2, closed at one end, a tight-fitting piston encloses an air column of length 7 dm. We press the piston inwards until the force we are exerting on the piston reaches 400 N.
During the compression, the temperature of the gas does not change. The external air pressure is
105 Pa.
a) What
pressure
will we exert on the gas?
b) What will be the pressure of the gas then?
c) What will be the volume of the gas?​

Amanometer is used to measure the air pressure in a tank. the fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 34 in. if the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the
