implications of open vs closed beakers

Why does an open beaker imply constant pressure? What does a closed beaker imply?

An open beaker implies constant pressure because the volume can be changed. A closed system is where energy can transfer in and out of the system.

An open beaker can remain at a constant pressure with its surroundings because it can exchange energy and matter to come to an equilibrium pressure state. A closed beaker implies that there is no exchange of matter between the beaker and its surroundings. However, there is an exchange of energy.
