Q. An ideal gas has an initial pressure of 3 pressure units and an initial volume of 4 volume units. The table gives the final the final pressure and volume of the gas (in those same units) in four, processes. Which processes start and end on the same isotherm [table] | $A$ | $B$ | $C$ | $D$ ; $P$ | 5 | 4 | 12 | 6 ; $V$ | 7 | 6 | 1 | 3 [/table]
A) $A$
B) $B$
C) $C$
D) $D$
Explanation
(c) For same isotherm; $T \rightarrow$ constant
$\therefore P \propto \frac{1}{V} \Rightarrow P_{1}V_{1} = P_{2}V_{2}$
