Answer:
Isobaric process
Step-by-step explanation:
The process in which the system pressure remain constant is called is called isobaric process. The word "iso"means same and baric means pressure.
At constant pressure, the work done is given by :
![W=p* \Delta V](https://img.qammunity.org/2020/formulas/engineering/college/c4gg3slqohi2ebnmay0e3eezzmdtxf9p6r.png)
Where
W is the work done by the system
p is the constant pressure
is the change in volume
So, the correct option is (c) " isobaric process ".
