Real Gas Behavior | The Compression Factor (Z) [Example #2]

The video tutorial explains the concept of the compression factor Z and its application in determining whether a gas behaves ideally or non-ideally. It uses an example problem involving carbon dioxide to calculate the real and ideal molar volumes, and subsequently the compression factor. The tutorial concludes by interpreting the compression factor to determine if attractions or repulsions predominate in the gas.

What is the primary purpose of calculating the compression factor Z in this context?

• To determine the temperature of the gas

• To find out if the gas behaves ideally

• To measure the speed of gas molecules

• To calculate the mass of the gas

How is the real molar volume of a gas calculated?

• By dividing the pressure by the temperature

• By multiplying the volume by the number of moles

• By dividing the actual volume by the number of moles

• By adding the volume and the number of moles

Which gas constant is used in the calculation of the ideal molar volume in this problem?

• 1.00 liter per mole

• 8.314 joules per mole Kelvin

• 0.08206 liter atmospheres per mole Kelvin

• 50.0 atmospheres

What does a compression factor Z less than 1 indicate about the gas?

• Attractions dominate in the gas

• The gas is at absolute zero

• The gas is ideal

• Repulsions dominate in the gas

If the compression factor Z were greater than 1, what would that imply?

• The gas is ideal

• Attractions dominate in the gas

• The gas is a solid

• Repulsions dominate in the gas
