The variation of compressibility factor 
with pressure ( 
in bar) for some gases are shown in the figure below. Identify the gases 
and 
respectively
A
real gas, 
B
ideal gas, 
C
ideal gas, 
D
real gas, 
Text Solution
Verified by ExpertsThe correct answer is:
B
The extent of deviation shown by real gases from ideal behaviour is measured in terms of compressibility fractor 
which is mathematically defined as follows:
For ideal gases, 
Easily liquefiable gases such as 
exhibit larger deviation as compared to gases such as
