MCQ
Figure shows the isotherms of a fixed mass of an ideal gas at three temperatures $T_A, T_B$ and $T_C$, then
- A$T_A > T_B > T_C$
- ✓$T_A < T_B < T_C$
- C$T_B < T_A < T_C$
- D$T_A=T_B=T_C$
✓
Answer
Correct option: B.
$T_A < T_B < T_C$
b
(b)
(b)
$\because P V=R T$
$\frac{R T}{V}=P$
$\because$ For constant $\frac{1}{V} \quad$ So, $P \propto T$
$\because P_C > P_B > P_A$ then
$T_C > T_B > T_A$
