A gas expands adiabatically at constant pressure such that its temperature `Tprop(1)/(sqrt(V))` , the value of `C_(P)//C_(V)` of gas is

Options

A. `1.30`
B. `1.50`
C. `1.67`
D. `2.00`

Answer

B

Explanation

`Tbar(V)^(gamma-1)` = constant `implies T prop V^(1-gamma)`
According to question , `T prop V^(1/2)`
Hence `1-gamma = -1/3 implies gamma 3/2 = 1.5`.
