Problem 7. A U-shaped manometer uses mercury. On the left side gas A is connected with a pressure of 39 cm Hg. On the right side, gas B is connected with a pressure of 1/3 Patm. If the mercury level is 14 cm higher on the right side than on the left side, determine the atmospheric pressure, Patm. Express your answer in units cm Hg.

Answer #1

Pressure of gas A on the left side = PA = 39 cmHg

Pressure of gas B on right side = PB = (1/3)Patm

Height difference in the U-manometer = H = 14 cm

The manometer uses mercury as it's liquid therefore,

Pressure difference between the left side and the right side = P = 14 cmHg

Patm = 75 cmHg

Atmospheric pressure = Patm = 75 cmHg

A long, clear, flexible tube is bent into a U shape(open at both ends), and we pour water into it (density 1000 kg/m3)until the water reaches the same level on both vertical sides. Now we pour a 7 cm column of mercury into the left side(density 13,600 kg/m3), which does not mix with the water. (a)When the fluids reach equilibrium, find the difference in elevation between the top of the mercury (on the left) and the top of the water...

Chapter 5- Gases 24. As weather balloons rise from the earth's surface, the pressure of th atmosphere becomes less, tending to cause the volume of the balloons to exand. However, the temperature is much lower in the upper atmosphere that at sea level. Would this temperature effect tend to make such a balloon expand or contract? Weather balloons do, in fact, expand as they rise. What does this tell you? 37. Freon-12 (CF2Cl2) is commonly used as the refrigerant in...
