Thermodynamic Processes

An ideal rigid diatomic gas $\left(\gamma = \frac{7}{5}\right)$ undergoes an adiabatic change. If the relation between temperature and volume is $TV^{x} =$ constant then the value of x is

Show answer and solution

Answer: (c)

Adiabatic: $TV^{\gamma-1} =$ const, so $x = \gamma - 1$ .
$x = \frac{7}{5} - 1 = 0.40$
So the answer is (c) 0.40.
