Thermodynamics Question 6
Question 6 - 2024 (30 Jan Shift 2)
Choose the correct statement for processes $A \& B$ shown in figure.
(1) $PV^{\gamma}=k$ for process $B$ and $PV=k$ for process $A$.
(2) $PV=k$ for process $B$ and $A$.
(3) $\frac{T^{\gamma}}{P^{\gamma-1}}=k$ for process $A$ and $P V=k$ for process $B$.
(4) None of these
Show Answer
Answer: (1)
Solution:
Steeper curve (B) is adiabatic
Adiabatic $\Rightarrow PV^{v}=$ const.
Or $P\left(\frac{T}{P}\right)^{v}=$ const.
$\frac{T^{v}}{P^{v-1}}=$ const.
Curve (A) is isothermal
$T=$ const
$PV=$ const.
