Question

What is a change that will not affect the pressure in a container

Answer 1

changing the material that the fluids container is made of.

Answer 2

Isobaric change will not affect the pressure in a container.

Step-by-step 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
`P\Delta V`, where
`\Delta V` is the difference in volume under constant pressure.
