Physics - Heat & Thermo Question with Solution | TestHub

Is an adiabatic process

$T{V}^{\gamma -1}=const\Rightarrow V{T}^{\frac{1}{\gamma -1}}=const$

$\Rightarrow$as T increase V decreases at non-uniform rate

In process$a\to b$P = constant as$V\propto T$

In process$c\to d$$P^{\prime }=$constant s$V\propto T$

But since slope of V - T graph$\propto \frac{1}{P}$

since slope of ab < slope of cd

$\Rightarrow P_{ab}>P_{cd}$

Also in adiabatic process$d\to a$as T is increasing V in decreasing

$\Rightarrow$P is increasing, so P - V diagram is as below
