Closed vs isolated systems

[Malia Shitabata 1F]

Can somebody explain the difference between closed and isolated systems? I don't really understand the difference based off of the textbook definitions.

[Shivam Rana 1D]

A closed system cannot exchange mass with its surroundings but it can exchange energy, while an isolated system cannot exchange either.

[Micah3J]

A closed system cannot exchange mass with its surroundings but it can exchange energy, while an isolated system cannot exchange either.

So what would be an example of a closed system and an example of an isolated system?

[KaleenaJezycki_1I]

A closed system cannot exchange mass with its surroundings but it can exchange energy, while an isolated system cannot exchange either.

So what would be an example of a closed system and an example of an isolated system?

An example of a closed system is an ice pack, like the shakeable ones that are in emergency kits, when you shake them they absorb heat from the surroundings which breaks down the inside and creates a cold ice pack. An example of an isolated system would be a sealed insulated thermos that you might put your tea or soup in to keep warm. This is thoroughly described in 4A.1 of the textbook ((:

[Elizabeth Harty 1A]

With a closed system, the mater is constant but every is allowed to be transferred to the surroundings. In an isolated system neither matter nor energy transfer is allowed.

[Wendy 1E]

Think of a closed system as a cup of coffee with a lid. It can exchange energy with its surroundings in the form of heat but cannot exchange matter because the lid is closed. Think of an isolated system, or something close to it, as a sealed hydro flask. You cannot exchange energy (hydro flasks essentially keep water cool) and you cannot exchange matter with its surroundings (because it is sealed).

[Matthew ILG 1L]

Dr. Lavelle gave a good example today in lecture. He said a closed system in a closed system, energy can still exchange with surrounding, but matter is not exchanged (i.e a sealed beaker of water. the beaker does not insulate)
In a isolated system, nothing exchanged with the surroundings. It is as if, as Dr. Lavelle said "a puffer jacket is wrapped around the closed beaker" so that no exchanges can be made with the beaker's surroundings (i.e matter or energy).
An example he gave of an isolated system was the combustion of glucose in a bomb calorimeter.

[Joanne Lee 1J]

A closed system is any system where energy can be exchanged with its surroundings. An example of this would be a sealed beaker of water. On the other hand, an isolated system nothing can be exchanged with their surroundings and an example of this would be combustion of glucose in a bomb calorimeter.

[Robert Tran 1B]

Closed systems can exchange energy with their surroundings. On the other hand, isolated systems cannot exchange energy with its surroundings. This means that closed systems can transfer heat, but isolated systems cannot.

[Amanda Mei 1B]

A closed system is physically closed but not thermodynamically closed, meaning that although matter cannot be exchanged between the system and its surroundings, energy can. An example would be a sealed beaker of water, which doesn't insulate, or a pan with a lid on top of it on the stove. An isolated system is both physically and thermodynamically closed. One example is a thermos, which insulates and doesn't allow transfer of energy (heat) or the physical contents inside.

[Leyna Dang 2H]

Closed systems are able to exchange energy, and therefore heat, with their surroundings. Isolated systems can't exchange energy with their surroundings.

[905373636]

A bomb calorimeter would be an isolated system; a closed system would be the ‘cup’ with the external pressure image.

[Matthew Tsai 2H]

A closed system allows for exchange of heat with its surroundings (has the ability to release and/or absorb heat) while an isolated system does not.

[Altamash Mahsud 1I]

A closed system is a system in which matter cannot be transferred between the system and the surroundings, but energy can be transferred between the two. In an isolated system, neither energy or matter can be transferred between the system and the surroundings.

[Nicholas_Gladkov_2J]

Can somebody explain the difference between closed and isolated systems? I don't really understand the difference based off of the textbook definitions.

I think that one of the best examples of a closed system is a thermometer. With a closed system, there is an exchange of heat, so with the thermometer heat is being exchanged with the contents in the thermometer, but the matter inside of the thermometer never leaves. With an isolated system there is no exchange of heat so like with a bomb calorimeter heat not exchange with the outside. If a thermometer was an isolated system, it would never show the temperature.

[Michellekim1H]

A way to understand the difference between a closed and isolated system could be used by some examples. For a closed system, think of an ice pack. A closed system is defined as a system that exchanges energy with its surroundings but no matter comes out of it. An ice pack is closed but can still exchange energy with its surroundings/the air/anything it comes into contact with. As for an isolated system, think of a thermos. Inside the thermos, the heat is trapped in and obviously, it's not exchanged with the surroundings. The definition of an isolated system is that nothing, both energy and matter, is exchanged with the surroundings.

[Radha Patel 4I]

open system - can exchange energy and matter with its surroundings. Ex. Coffee in a cup without a lid
closed system - can exchange energy but not matter with its surroundings Ex. Coffee in a cup with a lid on it
Isolated- cannot exchange energy and matter with its surroundings Ex. Hydroflask or seal covering the coffee in a cup so temperature doesn't change

[Tahlia Mullins]

A closed system has the ability to exchange energy with the surroundings, but not matter, while an isolated system cannot exchange either, such as a calorimeter.

[Lauren Stack 1C]

The main difference between a closed system and an isolated system revolves around energy. Both closed and isolated systems do not exchange matter (reactants/products) with the surroundings, but closed systems exchange energy with the outside world. Isolated systems do not exchange mass OR energy. Thus, the difference is ultimately that isolated systems exchange nothing with the surroundings, while closed systems exchange energy.
If you think of examples, it might help you remember. A beaker with a cap ensures that the matter inside of it remains constant, but the beaker itself can get hot or cold, impacting/releasing thermal energy into the world. This is a closed system. Conversely, a very good thermos maintains temperatures inside of it, because it insulates the contents, trapping both the matter and energy within the container.

[RobertXu_2J]

Closed systems can exchange energy with the environment, but isolated systems cannot. So, like heat for example.

[Kayla Maldonado 1C]

In a closed system, matter does not change, but the energy (heat) can with the surroundings. In an isolated system matter doesn't change and energy cannot change meaning that the system is insulated.

[Andres Merlos 2L]

A closed system cannot exchange matter with its surroundings, but it can exchange energy. An isolated system cannot exchange matter or energy.

[Daniela Shatzki 2E]

closed systems can exchange heat/energy with its surroundings but not actual substance. Isolated systems can exchange neither.

[Hannah Pham]

In a closed system, the matter within the system is constant but energy can be transferred from the system to surroundings and vice versa. In an isolated system, neither matter nor energy between system and surroundings are allowed.

[205389184]

One of the main differences is that closed systems cannot exchange mass with its surroundings however it can exchange energy, meanwhile isolated systems cannot exchange either.
