Question

The graph of pressure versus temperature $(P-T)$ for adiabatic process is best described by (use adiabatic constant $\gamma =\frac{3}{2}$

• A.
• B.
• C.
• D.

Answer 1

Answer: (C)

$P{T}^{\frac{\gamma }{1-\gamma }}=$ constant
$P{T}^{\frac{\frac{3}{2}}{1-\frac{3}{2}}}=$ constant
$P{T}^{-3}=$ constant
$P\propto T^3$
