**Explanation of Graphs and Diagrams:**

In this problem, no specific graphs or diagrams are provided. However, typically for an isobaric process, a Pressure vs. Volume (P-V) graph is useful. In an isobaric process, the graph would show a horizontal line indicating constant pressure while the volume changes from \(1.00 m³\) to \(3.00 m³\). 

Here's what to visualize:
- **Horizontal Line (Isobaric Process):** The line remains constant at 2.50 kPa along the vertical pressure axis while extending horizontally from 1.00 m³ to 3.00 m³ on the volume axis.

Understanding these principles will assist in solving the provided thermodynamics problems accurately.
