"For a given weight of gas, at a given temperature, the volume varies inversely as the pressure"

What law is best described the statement?

• Charles's Law

• Boyle's Law

• Avogadro's Law

Which of the following statement describes the Charles' Law?

• Under the same conditions of temperature and pressure, equal volumes of all perfect gases contain the same number of molecules

• For a given weight of gas, at a given temperature, the volume varies inversely as the pressure

• For a given weight of gas, at a given pressure, the volume varies directly as the absolute temperature

Select which one is the ideal gas law?

• PV=nRT

• PT=nRV

• 8.46 lb

• 23.26 lb

• 20.12 lb

• 32.24 lb

Which of the formula is for the density of perfect gas?

A gas mixture contains 60 wt% of methane. What is the weight of methane if the total gas mixture is 100 lb?

• 30 lb

• 40 lb

• 59 lb

• 60 lb

• 1 lb

• 2.45 lb

• 16 lb

• 12.46 lb

From chart estimate the critical pressure (Pc) and critical temperature (Tc) of gas with a specific gravity of 0.6?

• Ppr = 3.00

  Tpr = 1.32

• Ppr = 3.70

  Tpr = 1.56

• Ppr = 2.56

  Tpr = 1.46

• Ppr = 4.20

  Tpr = 2.56

If the gases' Ppr = 3.70 and Tpr = 1.56, determine the compressibility factor, z of the gas

• z = 0.85

• z = 0.8

• z = 0.9

• z = 0.87
