Answer:
changing the material that the fluids container is made of.
Isobaric change will not affect the pressure in a container.
Explanation:
According to Charles Law, at constant pressure, for same mass, the volume is directly proportional to its temperature. A change that happens without affecting the pressure in a container that is at a constant pressure is an isobaric process (a thermodynamic process).
An isobaric expansion of a gas requires heat transfer under constant pressure, and the work done is [tex]P\Delta V[/tex], where [tex]\Delta V[/tex] is the difference in volume under constant pressure.
