Thermodynamics Question 322
Question: P-V plots for two gases during adiabatic process are shown in figure. Plots 1 and 2 should correspond, respectively, to
Options:
A) He and
B)
C) He and Ar
D)
Show Answer
Answer:
Correct Answer: B
Solution:
[b]Slope of adiabatic curve
So,
[as
From the graph it is clear that slope of curve 1 is less, so this should be adiabatic curve for diatomic gas (i.e.,
Similarly, slope of curve 2 is more, so it should be adiabatic curve for monoatomic gas (i.e. He).
