Question

write three cases of behaviour of gases depending of gases depending on the value of compressibility factor

​

Answer 1

Answer:

• the value of Z tends toward 1 as the gas pressure approaches 0, where all gases tend toward ideal behavior
• the value of Z is less than 1 at intermediate pressures because the intermolecular forces of attraction cause the actual volumes to be less than the ideal values
• the value of Z is greater than 1 and ultimately tends toward infinity at high pressures because the intermolecular repulsive forces cause the actual volumes to be greater than the ideal values
• Equation: Z=PVm/RT
