Q.
This graph expresses 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) Isochoric
B) Isobaric
C) Isothermal
D) Cyclic
Explanation
(b)
At $\mathbf{A} \rightarrow$ temperature $= T$, volume $= V$, pressure $= p_{1}$
At $\mathbf{C} \rightarrow$ temperature $= 2T$ volume $= 2V,$ pressure $= p_{2}$
$\frac{p_{1}V}{T} = \frac{p_{2} \times 2V}{2T}$
$p_{1} = p_{2},\ ie,$ system is isobaric
