closed systems

[005199302]

Are closed systems either at constant volume nor at constant pressure?

[EllerySchlingmann1E]

Closed systems can have constant pressure, volume or neither. However, one of the more common examples of a closed system, a beaker with a piston, is usually related to a question in which there is constant pressure.

Closed is able to be influenced by heat, however no outside mass can be added. Additionally, volume and pressure are able to stay constant or change.

[Bruce Chen 2H]

Closed systems can have either constant pressure and constant volume. There may also be times where both are constant.

[Nicholas Le 4H]

Closed systems can have constant or changing pressure or volumes.

They can have both. However heat can be transferred in a closed system.

[Hadji Yono-Cruz 2L]

They can have both be constant or changing.
