closed system

[Alison Trinh 1E]

Why is it that closed systems prevent volume changes?

[vpena_1I]

By definition, a closed system does not allow for the exchange of matter. A closed water bottle is an example of a closed system, its volume will not change over the course of the reaction.

Because it doesn't allow for the exchange of matter. For example, let's say you have a shampoo bottle and it falls off the rack while you are taking a shower. Assuming the bottle is capped (closed system) the shampoo will not leak out of the bottle because the bottle doesn't allow that to happen!

[Jessa Maheras 4F]

Actually, closed systems don't prevent volume changes! A system can change in volume and still be closed, as long as no matter is exchanged between the system and surroundings. (Think of a piston)

[Joshua_Chan_3K]

By definition, a closed system is talking about something like a sealed metal box. Mainly because one of the points of using a closed system is the ability to measure changes in pressure. I don't know if something like a balloon could be called a closed system but I feel like it could so I'm not altogether sure if my explanation is correct.

[kristinalaudis3e]

Closed systems have a fixed amount of matter and don't allow for the exchange of matter. A clear example would be like the water bottle example mentioned above. A closed water bottle doesn't allow the water inside to leak!

[Hasan Mirza 3F]

Closed systems have a fixed amount of matter and allow the transfer of energy as heat. Volume can actually be changed in such a system but it would most likely be as a result of a change by the experimenter such as moving a piston up or down to change volume and pressure.

[Alexis Sanft 1E]

Closed systems have a fixed amount of matter and allow the transfer of energy as heat. Volume can actually be changed in such a system but it would most likely be as a result of a change by the experimenter such as moving a piston up or down to change volume and pressure.

So, does the transfer of energy as heat not effect the volume or the state of matter?

[305572629]

They don’t allow for matter to be exchanged inside and outside of the system!

[Hana Sigsbee 3B]

A closed system prevents volume change because there is no exchange of matter with the system's surroundings so nothing can leave the system so its volume stays consistent.

[manisha_joseph_1H]

A closed system means that there is no exchange of matter between the system and its surroundings, therefore the volume of the system cannot change.

[Leyla Anwar 3B]

Closed systems have a fixed amount of matter and allow the transfer of energy as heat. Volume can actually be changed in such a system but it would most likely be as a result of a change by the experimenter such as moving a piston up or down to change volume and pressure.

If a water bottle were heated and some of the water turned to vapor would the volume not change (still inside the closed bottle)? and with that the state of matter from liquid to gas. Im not sure that "matter" would actually change though, there should still be the same amount of matter.

[sophia kosturos 2B]

closed systems prevent volume changes because the system is sealed and thus does not exchange any matter between the system and its surroundings, which would not allow for changes in volume.

[Jaden Joodi 3J]

Because a closed system disallows matter from being exchanged, it is impossible for the volume in the system to change.

[Abhinav Behl 3G]

By definition, a closed system does not allow for the exchange of matter between the system and its surroundings. This makes sense because the system will be sealed, and therefore you should not expect any matter to leave the system, or enter the system from its surroundings.

[Lauren Sarigumba 1K]

an open system can exchange both matter and energy with the surroundings. However, a closed system has a fixed amount of matter and can only exchange energy with the surroundings. the fixed amount of matter implies that the volume is constant.

[Sam Wentzel 1F 14B]

I believe closed system's volume can be changed through compression if the substances are gases. For solids and liquids, compression barely effects their volume so they are considered to have constant volume.

[Samir 3I]

A closed system has a fixed volume of matter in the system and this matter is unable to physically transfer/interact with the outside environment. Only energy can be transferred in or out of the closed system

[Nicoli Peiris 1B]

A closed system means no matter in or out which means no volume change.

[Eileen Quach Dis 2A]

A closed system has a fixed amount of matter because the system is sealed off, so therefore, substances can't be added or taken away and the volume doesn't change.

[DPatel_2L]

Closed systems do not allow for an exchange of matter.

[Aanya Tanti 3C]

Closed systems do not allow the transfer of matter from inside or outside. Thus, volume would stay the same.

[Anna Yang 1A]

For example, an open system would be a beaker of water without a lid. In this scenario, water can evaporate. In a closed system, the beaker would be sealed and volume would not be lost through that process.

[SavannahScriven_1F]

I'm a little confused on this too. I think that only certain closed systems prevent volume changes (e.g a sealed beaker). Systems that are closed with a piston do allow for volume changes due to expansion (of gases).

[aashmi_agrawal_3d]

This is because there is a fixed amount of matter so the volume can't change as well.

[FionaHunter21]

What's the difference between a closed system and an isolated system? Can an isolated system not absorb heat or lose heat to its surroundings?

[Taylor Newville 1C]

What's the difference between a closed system and an isolated system? Can an isolated system not absorb heat or lose heat to its surroundings?

An isolated system is insulated, which means it can't exchange matter or heat with the surroundings. A closed system is not insulated so the only constant is matter, not heat.

[Ivy Tan 1E]

Hi!
Closed systems prevent volume changes because it does not allow for any exchange of matter between the system and the surroundings. Hope this helps!!

[Jamie Wang 3C]

imagine you have a water bottle that is sealed closed, you could put the water bottle in another tub of hot water to heat the water inside, but cannot change the volume of the water inside without taking off the lid

[Inderpal Singh 2L]

Closed systems do not allow the matter to "escape" into the surroundings. However, the energy can still be exchanged into the surroundings.

[Lorraine Medina 3E]

Closed systems don't allow for the exchange of matter. hope this helps!

[Eric Cruz 2G]

For a closed system, you cannot add matter to the system, volume included. Therefore, no you cannot change the volume of the system.

[David Jen 1J]

In a closed system, matter cannot be exchanged, thus volume won't change as well

[DavidTabib 3H]

Being a closed system means that no matter can go in and out, therefore the volume does not change.

[Joshua Swift]

A closed system does not allow the exchange of matter so the volume remains constant.

[Justin Lin 1B]

In a closed system, matter can't be transferred in or out of the system. There is no exchange of matter between the system and the surrounding. This means that the volume can't change because matter doesn't change.

[Mackenzie Stockton 2H]

Closed system means matter is not exchanged between the system and surroundings, so Volume cant be exchanged.

[Lung Sheng Liang 3J]

A closed system does not interact with any matter outside of it.

[Sarah Huh 1K]

A closed system does not allow exchange with its surroundings.

[Jack_Pearce_2H]

Closed systems do not allow for the transfer of matter in or out of said system. A volume change usually entails adding or removing gas (matter) so they closed systems are constant volume.

[James_Hankee_1C]

In a closed system, there is no exchange of matter from the surroundings. The overall volume in whatever state it is in stays the same in the closed system. The states may change in a reaction however, there is no volume change.

[Aanya Tanti 3C]

A closed system doesn't allow for the exchange of matter, which means that volume will stay constant.

[kristinalaudis3e]

A closed system does not allow for an exchange of matter. Think of “closed doors” as nothing comes in!

[Abraham De Luna]

A closed system would not allow for an exchange in matter because it is a fixed amount.
