What is an isobaric process ?

Explanation

### Step-by-Step Solution:

1. **Definition of Isobaric Process**:
- An isobaric process is a thermodynamic process in which the pressure remains constant throughout the entire process. The term "isobaric" comes from the Greek words "iso," meaning equal or constant, and "baros," meaning pressure.

2. **Understanding the Graph**:
- In an isobaric process, if we plot a graph with pressure on the y-axis and volume on the x-axis, the graph will be a horizontal line. This indicates that as the volume changes, the pressure does not change.
