Question:
5 moles of a gas is allowed to pass through a series of changes as shown in the graph, in a cyclic process.
The processes \(C \rightarrow A\), \(B \rightarrow C\), and \(A \rightarrow B\) respectively are:
\[
\text{(Volume = vertical axis, Temperature = horizontal axis)}
\]

Show Hint
Always identify the nature of the graph:
Vertical line Isothermal (T constant)
Horizontal line Isobaric (P constant)
Straight vertical or horizontal change Isochoric or Isothermal depending on which axis is constant.
Vertical line Isothermal (T constant)
Horizontal line Isobaric (P constant)
Straight vertical or horizontal change Isochoric or Isothermal depending on which axis is constant.

The Correct Option is D
Solution and Explanation
Step 1: Analyze segment \(C \rightarrow A\)
In this path, the curve is vertical, meaning temperature is constant while volume changes.
Hence, the process is Isothermal. Step 2: Analyze segment \(A \rightarrow B\)
Here, volume increases but temperature remains constant (horizontal line),
which is a characteristic of an Isobaric process. Step 3: Analyze segment \(B \rightarrow C\)
This segment shows a straight line with constant volume, while temperature decreases.
Therefore, the process is Isochoric. Step 4: Conclusion
The sequence of processes is: Isothermal (CA), Isobaric (AB), Isochoric (BC).
