The basic barometer can be used as an altitude measuring device in
airplanes. The ground control reports a barometric reading of 753mmHg
while the pilot's reading is 690mmHg. Estimate the altitude of the plane
from ground level if the average air density is 1.20 kg.m-3 and the
barometer fluid is mercury, PHg=13600 kg.m3.
To solve this problem determine the atmospheric pressure on the ground
and then in the air using the barometric pressure readings.
Then using the pressure difference between the ground and the plane, the
altitude can be derived by considering a column of air from the ground up
to the plane, of constant density, in a similar manner to the barometer.

The figure shows a 50.-kg frictionless cylindrical piston that floats on 20 mol of compressed air at 45.°C. How far does the piston move if the temperature is increased to 600 °F? (This is an Isobaric process and the piston is at sea level under an atmospheric pressure of 101.3 kPa). The values given in the figure are: 50. Kg, 30.°C, and 10. cm.
