Q98
On a P-V diagram of an ideal gas, suppose a reversible adiabatic line intersects a reversible isothermal line at point A. Then at a point A, the slope of the reversible adiabatic line ( P V )_ S and the slope of the reversible isothermal line ( P V )_ T are related as (where, y = C_ p C_ v )

A.
B.
C.
Answer
D.
Answer: Option C
Solution
Answer: Option C
Solution:
For an adiabatic process → = constantFor an isothermal process → = constant
So, slope for adiabatic process in plane is
Slope for isothermal process is
Hence,
