Accepted Answer

Steeper curve (B) is adiabatic
Adiabatic $\Rightarrow \mathrm{PV}^v=$ const.
Or $\mathrm{P}\left(\frac{\mathrm{T}}{\mathrm{P}}ight)^v=$ const.
$\frac{\mathrm{T}^v}{\mathrm{P}^{v-1}}=	ext { const. }$
Curve (A) is isothermal
$\mathrm{T}=$ const.
$\mathrm{PV}=$ const.

Answer

$P V=k$ for process $B$ and $A$.

Answer

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

Answer

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

Answer

$P V^{\prime}=k$ for process $B$ and $P V=k$ for process $A$.
