In the polytropic process P V 2 1 = constant , does the gas get heated or cooled when its volume increases?

T ∝ P V = V − 2 1 C , so T ∝ V 2 1 . The temperature rises with volume. A.

In the polytropic process $P V^{\frac{1}{2}} = constant$ , does the gas get heated or cooled when its volume increases?

Answer:

Solution:

$T \propto P V = \frac{C}{V ^{- \frac{1}{2}}}$ , so $T \propto V^{\frac{1}{2}}$ . The temperature rises with volume. A.
