Question

This graph express the various steps of the system containing 1 mole of gas. Which type of process system has when it moves from C to A?

• A. Isothermal
• B. Adiabatic
• C. Isobaric
• D. Isochoric

Answer 1

Answer: (C)

At $A$, temperature $=300K$, volume $=10L$, Pressure $=P_1$

At $C$, Temperature $=600K,$ volume $=20L,$ Pressure $=P_2$

$\frac{P_1{V}_1}{T_1}=\frac{P_2{V}_2}{T_2}$

$\Rightarrow \frac{P_1\times 10}{300}=\frac{P_2\times 20}{600}$

$P_1=P_2$

Thus; the process is isobaric.
