A gas expands adiabatically at constant pressure, such that its temperature

\propto \frac{1}{{\sqrt V .}}

) . The value of

{C_p}/{C_v}

of the gas is

View answer and explanation

Correct option: B

1.5

Option B (1.5) is correct because, by combining the adiabatic expansion equation with the given temperature-volume relationship, the ratio of specific heats (Cp/Cv) is found to be 1.5.
