MCQ
Pressure-temperature relationship for an ideal gas undergoing adiabatic change is $\left(\gamma=C_p / C_v\right)$
  • A
    $P T^\gamma=$ constant
  • B
    $P T^{-1+\gamma}=$ constant
  • C
    $P^{\gamma-1} T^\gamma=$ constant
  • $P^{1-\gamma} T^\gamma=$ constant

Answer

Correct option: D.
$P^{1-\gamma} T^\gamma=$ constant
(d)
$PV^\gamma =constant $
$\Rightarrow P (\frac{RT}{P})^\gamma=\text { constant } $
$\Rightarrow P^{1-\gamma} T^\gamma=\text { constant. }$
