Question

An ideal gas has an initial pressure of 3 pressure units and an initial volume of 4 volume units. The table gives the final pressure and volume of the gas (in those same units) in four, processes. Which processes start and end on the same isotherm

• A. A
• B. B
• C. C
• D. D

Answer 1

The correct option is C C

For same isotherm ; T $\to$ constant
$\therefore P\propto \frac{1}{V}\Rightarrow P_1{V}_1=P_2{V}_2$
