Corresponding to isobaric process match the following two columns.

Options

A.
B.
C.
D.

Explanation

To solve the question regarding the matching of the isobaric process with the corresponding graphs, we need to understand the characteristics of an isobaric process and how it relates to the various graphs provided.

### Step-by-Step Solution:

1. **Understanding Isobaric Process**:
- An isobaric process is one in which the pressure (P) remains constant throughout the process. This means that any changes in volume (V) and temperature (T) must occur while keeping the pressure fixed.

2. **Analyzing the Graphs**:
- We are given two columns to match. The first column likely contains different types of graphs (P-V, T-V, T-P, etc.), and the second column contains descriptions or equations that correspond to these graphs.

3. **Matching P-V Graph**:
- For a P-V graph in an isobaric process, the pressure is constant. Therefore, the graph will be a horizontal line at the value of the constant pressure. This means that the correct match for the P-V graph is the one that states "P is constant".

4. **Matching T-V Graph**:
- In an isobaric process, we can derive that the volume (V) is directly proportional to the temperature (T) when pressure is constant, according to the ideal gas law (PV = nRT). However, this relationship does not yield a straight line in a T-V graph; instead, it indicates that the volume increases with temperature. Thus, this match is incorrect.

5. **Matching T-P Graph**:
- In a T-P graph, if the pressure is constant, the graph will show a horizontal line at the constant pressure level as temperature changes. Therefore, this match is correct.

6. **Final Matching**:
- Based on the analysis:
- The correct matches are:
- P-V graph: "P is constant" (Match with B)
- T-P graph: "P is constant" (Match with D)

### Conclusion:
The correct answers are B and D.
