question on lecture notes about closed system

Postby Mallika Singh 1G » Mon Feb 03, 2020 2:08 pm

For my notes under the definition of a closed system, I have (for the example specifically) "Ex: sealed beaker of water: Beaker does not insulate"
I'm confused as to what a lack of insulation has to do with it being a closed system? Or do I have the notes wrong? Thank you for your help!

A closed system means that the matter can not leave and matter can not come in. However, energy in the form of heat can leave/enter. That's probably why you said does not insulate, because the temp can change.

If there was insulation, then it would be an isolated system, as there would be no change in matter or heat.

It is important to note that the beaker does not insulate because this ensures that transfer of heat can still occur (otherwise it would be an isolated system).

the beaker not being insulated is important for its distinction from an isolated system, since as it is not insulated heat/energy can be exchanged.

A closed system cannot exchange matter with its surroundings but can exchange heat. Therefore, the lack of insulation for the closed system allows for heat exchange between the closed system and the surroundings. If it was completely insulated, it would be an isolated system because it cannot exchange matter or heat with its surroundings.
