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 (‚à ÇP/‚à ÇV)S and the slope of the reversible isothermal line (‚à ÇP/‚à ÇV)T are related as (where, y = Cp/Cv))$?

• A. (‚Äö√ √áP/‚Äö√ √áV)S = (‚Äö√ √áP/‚Äö√ √áV)T
• B. (‚Äö√ √áP/‚Äö√ √áV)S = [(‚Äö√ √áP/‚Äö√ √áV)T]Y
• C. (‚Äö√ √áP/‚Äö√ √áV)S = y(‚Äö√ √áP/‚Äö√ √áV)T
• D. (‚Äö√ √áP/‚Äö√ √áV)S = 1/y(‚Äö√ √áP/‚Äö√ √áV)T
