Choose the correct statement for processes A & B shown in figure.

Choose the correct statement for processes $A$ & $B$ shown in figure.

$P V^{γ} = k$ for process $B$ and $P V = k$ for process $A$ .
$P V = k$ for process $B$ and $A$ .
$\frac{P^{γ - 1}}{T^{γ}} = k$ for process $B$ and $T = k$ for process $A$ .
$\frac{T^{γ}}{P^{γ - 1}} = k$ for process $A$ and $P V = k$ for process $B$ .

Solution

Steeper curve (B) is adiabatic
For adiabatic $\Rightarrow {PV}^{γ} =$ constant
and curve (A) is isothermal. Therefore,
$T =$ constant
$\Rightarrow P V =$ constant
