Re: closed vs isolated
Closed means that energy can exchange with the surroundings. It will be sealed but not completely... Isolate means completely sealed, so nothing can exchange with the surroundings (ex. bomb calorimeter). Isolated is even more "protected" from transfer into the surroundings if you will.

Re: closed vs isolated
Closed can not interact with the environment at all. Isolated can interact slightly.
Re: closed vs isolated
A closed system can transfer energy (heat or work) but not matter with its surroundings.
An isolated system cannot transfer energy or matter with its surroundings.
An isolated system cannot transfer energy or matter with its surroundings.

Re: closed vs isolated
Heat can be transferred with the surroundings in a closed system but matter cannot. Neither can be transferred with the surroundings in an isolated system.
Re: closed vs isolated
An example of a closed system would be and ice pack used to reduce swelling on injuries (energy can be transferred in and out of the system) and an example of an isolated system would be a thermos with hot liquid in it (no heat/energy/matter can go in and out of the system into the surroundings).

Re: closed vs isolated
Closed allows only energy transfer while isolated does not allow the transfer of energy nor matter.

Re: closed vs isolated
The main difference is that heat exchange can still occur in a closed system but not in an isolated system.

Re: closed vs isolated
In an isolated system, no exchange of any kind can happen between the system and the surroundings, while in a closed system, energy can be exchanged between the system and the surroundings. The examples given in class were the bomb calorimeter being a isolated system while a sealed beaker is a closed system.

Re: closed vs isolated
In an isolated system, there can be in interaction between the system and its surroundings. In a closed system, there can be interaction with the surroundings.

Re: closed vs isolated
Isolated systems are completely sealed and closed off. Imagine a test tube with a lid on it, then wrapped completely in a "puff jacket" as Dr. Lavelle said in his in class example from a few weeks ago. It does not interact with its environment at all.

Re: closed vs isolated
A closed system is when a system can only transfer energy (like heat) with its surroundings, meanwhile an isolated system can't transfer anything with its surroundings.

Re: closed vs isolated
Isolated systems do not interact with the environment around it. A closed system can transfer energy.
