Is thermal mugs an example of an isolated system?

[Jenaye Brelland 2I]

You know how travel mugs are being designed to able to greater maintain the temperature of your beverage? Wouldn't that be an example of an isolated system because mass and heat are not being exchanged (At least we hope so)?

[Jenaye Brelland 2I]

The ones that have a lid and are for travel.

[Katie Nye 2F]

Yes! If the lid is closed and no energy/heat is allowed to escape then it is an isolated system.

[Charlie Russell 2L]

It's not a perfect isolated system since that doesn't exist in real life but it's pretty close! The long the heat stays in that mug, the closer to a perfect isolated system it is!

[Aarushi Verma 2I]

A thermos or any insulated sealed container would be as close to a real isolated system because no energy can be transferred from the system to the surroundings and no matter can be exchanged either.

[Madeline Louie 1B]

Since isolated systems don't exist in real life, travel/thermos mugs are as close to an isolated system as possible. They (to the best of their abilities) prevent an exchange of heat/energy and matter, making them an isolated system.

[Jiwon_Chae_3L]

In a perfect world where no heat or matter is lost through the mug, then it would be an isolated system.

[Andy Hon 3E]

Yes! That would be an example of an isolated system. Although some heat and energy may be scaping through pressure holes etc, it is a good example concept-wise.

[Grecia Velasco 1G]

Yes! No heat/energy or matter can enter or exit the system in the mug so it is an isolated system :) unless you open it! Then it would be an open system.

[Samudrala_Vaishnavi 3A]

Yes, they are considering that they don't exchange heat or energy with the surroundings (made to keep your beverage the same general temperature or do any work (change the mass of the substance in a container) since it has a lid.

[Brianna Chen 3F]

Yes, in the context of this class, we usually refer to thermals as isolated systems as long as they are closed/sealed on top.

[Abby Lam 3F]

Yes, I think you're right since mugs have a lid.

[aashmi_agrawal_3d]

I think so as long as the lid is closed.

[Anna Yang 1A]

They served as a pretty good example of one for an everyday object if they are closed and insulated.

[Namita Shyam 3G]

Yep, I think so. If material isn't going in or out, and if heat isn't going in or out, then yes, this would be an isolated system.

[Britney Tran IJ]

yep as long as there is no way for it to escape through the lid

[Madison Muggeo 3H]

If the lid is closed, and the mug is of high enough quality then yes, it is an isolated system.

[Norah Gidanian 3D]

Yes. If it is closed then there is no way for matter or energy to be exchanged with the surroundings

[darchen3G]

No, it is not isolated because even if the lid is closed there is still a small amount of heat exchange with the surroundings.

[Sreeram Kurada 3H]

Yes since energy and matter can't be exchanged.

[Justin Lin 1B]

It could be an isolated system if the lid is on. That way, no matter or energy can be transferred between the system and the surrounding.

[Will Skinner]

It is a good illustration of an isolated system, but it technically would be a closed system that allows minimal heat transfer to its surroundings. If you put a hot beverage in the thermos it will eventually cool, but slowly. However, if there is a thermos that is truly an isolated system, I would definitely buy it!

[Talia Dini - 3I]

Yes, as long as the lid is on, a thermal mug would be an example of an isolated system because energy and matter can not be exchanged.

Yes. I think we are getting closer and closer to developing more efficiently thermal mugs!

[Anthony_Sandoval_1D]

Yea, a thermal mug would be an excellent example of an isolated system as nothing comes in or out! A thermal mug without a lid would be an open system.

[Sara Sandri 2B]

Yup! no heat and energy can exit the system (as long as it has a lid). That is the definition of an isolated system.

[Brian Bui 3H]

Theoretically it would not exchange matter or energy with its surroundings, but in reality I don't think I know of any that does it 100% effectively. I think it would sell pretty well if it was capable of doing so! :P

But aside from that, I believe thermal mugs are generally used as examples of isolated systems, assuming they have 100% effectiveness.

[jia207]

As long as the lid of a thermal mug is on and sealed properly, it would be an example of an isolate system because there is no heat transfer from the system and its surrounding.

[Mursall M 2A]

If the lid is secured, then it would be considered an isolated system since no heat or energy is being exchanged with the surroundings!

[Jacob Schwarz-Discussion 3I]

It would be very near to an isolated system. No mass is exchanged and the longer heat is contained in the thermal mug, the closer it is to an isolated system.

[Chudi Onyedika 3A]

Yes, as long as there is a closed lid to retain the matter and the mug retains all of the heat.

[Kathy_Li_1H]

Hi! I believe if the thermal mug is completely sealed then yes it would be considered an example of an isolated system.

[James_Hankee_1C]

If the mug has a lid and no heat can escape it would be an isolated system. It would most likely be a closed system as opposed to an isolated system as heat will eventually escape from the system over time.

[Matlynn Giles 2E]

A mug with a lid would be an example.

[Jeremy Wei 2C]

Yes, if the mug cap is sealed then the thermal mug would be an example of an isolated system.

[OmarArafat_2K]

Yes! As long as no heat or energy is able to travel between the inside and outside.

[FrancescaHawkins2H]

I think someone mentioned this above, but truly isolated systems don't necessarily exist (and heat will eventually escape the mug), however, this is a really good example and is super close to one!

[Linette Choi 3L]

Yes, I would consider it an isolated system since no heat is leaving or entering the mug.

[Gicelle Rubin 1E]

It would if no heat is moving around! :)
