Q. 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?Chemistry Question Image

Thermodynamics

Solution:

At $A$, temperature $=300 \,K$, volume $=10\, L$, Pressure $= P _{1}$

At $C$, Temperature $=600 \,K ,$ volume $=20 \,L ,$ 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.
