Vapor vs gas

[Neha Gupta 2A]

Is there a difference between vapor and gas or are they the same thing?

[Simi Kapila_3E]

Vapor is just another way of saying a substance is in the gas phase. So yes, they are the same thing.

[Abby Lam 3F]

I think for the purposes of this class vapor and gas are the same thing.

[Norah Gidanian 3D]

They are the same thing just a different way of saying them. They are both the same phase

[DMaya_2G]

Both vapor and gas are in the same phase, so they both mean the same thing.

[Adrienne Yuh 2B]

They are both the same thing!

[OwenSumter_2F]

To go into more detail, in relations to phase changes vapor is more commonly used while gas is more commonly used in most other senses.

[Kimiya Aframian IB]

Is there a difference between vapor and gas or are they the same thing?

Hello! Vapor and gas can be used interchangeably. Hope this helps!

[Karl Yost 1L]

They're interchangeable :)

[Samiha Molla 3G]

I think they are used interchangeably like the others said! You also might see something referred to as a vapor when it's in the gaseous state (like "water vapor" when H20 is in a gas state).

[VincentLe_3A]

Yes, I believe both terms mean the same thing since it is in the same phase.

[Ariel Guan 1H]

i think they are the same thing

[Allan Nguyen 2G]

They're essentially the same thing

[Andy Hon 3E]

Vapor and gas can be used the same way.

[Kayle Lim 2C]

Vapor is a form of gas and for the topics we have covered so far when vapor is mentioned in a problem it is safe to assume they are talking about gas! For now I don't think there needs to be any specification on how they are alike or different.

[Lorraine Jiang 2C]

Hi! I think vapor and gas are the same things. But for this class, we will use vapor instead of gas because Dr.Lavelle used this term in his lectures.

Hope it helps!

[Anthony_Sandoval_1D]

The terms are pretty much interchangeable.

[Claudia_Danysh_2B]

They are the same! I was also confused about this before

[ellenulitsky Dis 1I]

Yes, they are the same thing and are used interchangeably! Hope this helps.

[Jordan Tatang 3L]

like the others said the two terms are synonymous

[aashmi_agrawal_3d]

I think vapor and gas are the same thing.

[Yeonjoo Kim 2B]

Yes, they can be used interchangeably!

[Joshua Swift]

Vapor and gas are interchangeable. So when they say enthalpy of vaporization, they mean the phase change from a liquid to the gas state.

[Aayushi Jani 3A]

Yes they are the same thing!

[Jiapeng Han 1C]

I think for the sake of this course, vapor and gas are the same thing. However, at least for me, I think gas typically refers to something that is naturally in gas phase, such as nitrogen and hydrogen, while vapor refers to something that is "vaporized" into gas, such as water vapor and iodine vapor.

[Chudi Onyedika 3A]

No, vapor and gas is the same thing.

[Jason_John_2F]

i think the terms refer to the same thing in this class

[Sabrina Galvan 3J]

They are both used for the same phase of a substance when it goes from a liquid to a vapor/gas.

[Jalaia Jackson 2G]

Agreeing with everyone else, yes they refer to the same thing. Good question.

[chinmayeec 2H]

In this class, as everyone else mentioned, they'll essentially refer to the same thing. I think vapor may refer to something that underwent a phase change from liquid to gas (vaporization).

[Ethan Laureano 3H]

So then what would be the difference between vaporization and evaporation? Are they one in the same or are there differences?

[Catherine Bubser 2C]

We would treat these as the same state, correct?

[Sabrina Galvan 3J]

We would treat these as the same state, correct?

Yes

[Katie Le 3K]

Yes they are synonymous.

[reyvalui_3g]

They are essentially the same thing.

[Joel Meza 3I]

Yes, they are the same, they both refer to something in the gaseous state.

[Mari Williams 1K]

Same thing! We just tend to say water vapor instead of water gas lol

[Astha Patel 2J]

Yes! Vapors are gases.

[Keshav Patel 14B 2B]

Vapor and Gas are the same thing, if it’s water vapor it is water in its gas phase.

[Alexandra Salata 2L]

Vapor and gas are the same thing, so if in a question they say something has been vaporized, it has just turned from a liquid to a gas.

[Neel Bonthala 2G]

Hi! Yes, both words are interchangeable.

[Nathan Lao 2I]

For the most part and in this class specifically, a gas and a vapor are synonymous. I think the technical difference is that vapors are the gas phase of a substance that would usually be liquid at room temperature/standard conditions.

[Justin Zhang_1A]

A vapor and a gas are the same thing

[MCalcagnie_ 1D]

I believe vapor is used in the description of a phase change where gas is used to describe the state/phase itself. They are essentially the same thing.

[Alexis Sanft 1E]

Are the only possible changes of substances those of gas, liquids,and solids converting into one another? Are there any other ones?

[Sahaj Patel Lec3DisK]

They are both the same thing! Vapor is more often sued to describe a liquid that has recently entered the gas phase. But, at the end of the day, they are the same thing!

[Presley Gao 2C]

No, there is not a difference between vapor and gas - they are the same thing and are considered interchangeable with each other and vice versa.

[Christine Ma 3L]

I think for the purposes of this class, the two are the same thing since they share similar properties. But gases are a state of matter, and vapors usually coexist in equilibrium with their liquid/solid states but gases don't. Vapor suggests that the substance has undergone a phase change, but gas does not.

[Tobie Jessup 2E]

They are the same thing.

[Lauren Strickland 1B]

Yeah they are the same thing.

[Nina Ellefsen 2D]

Yeah basically the same thing :)

[Diana Aguilar 3H]

Like many have stated before, there is no difference between vapor and gas, they mean the same thing :)

[joshtully]

Vapor and gas are the same thing.

[Riddhi Mehta 2C]

Does vapor usually refer to water or can it refer to any other element as well?

[Daniel Huynh 2J]

A vapor is basically the same thing as a gas.

[Izamary Marquez 2H]

Does vapor usually refer to water or can it refer to any other element as well?

I looked online and found that in general, vapor is a mixture of two or more different phases at room temperature, and these phases are typically in liquid and gaseous phases. On the other hand, gas usually contains a single thermodynamic state at room temperature. So in short, yes, vapor will tend to have H2O as part of the mixture.

[Aditya Sundaram 3D]

Is there a difference between vapor and gas or are they the same thing?

Nope. These two are the same thing!

[Aditya Sundaram 3D]

Does vapor usually refer to water or can it refer to any other element as well?

I think for this class we can say it refers to any element.

[Sejal Parsi 3K]

I believe vapor and gas are in the same phase so they are interchangeable in this class.

[David Y]

Yes vapor is in the gas phase

[Jeremy Wei 2C]

Yeah, if I'm not wrong vapor and gas refer to the same thing.

[Shreyank Kadadi 3K]

Yes, both of the words are equivalent for the purposes of this class!

[Colin Squire 3B]

Vapor and gas are the same thing, they are just said differently!

[Carly_Lipschitz_3H]

Vapor and gas are the same thing.

[Mina Tadros 3L]

Vapor and gas are the same thing.

[Ziyan Peng 3A]

Yes they are the same. Think about how water vapour is just another way of saying H2O(s), or the gas form of water.

[Rob Tsai 2F]

Both terms are interchangeable. I think it just has to do with the context/topic. Vapor is often times used when talking about phase changes (i.e. vaporization of water), while I feel like gas is used when it's being manipulated in a system. you rarely hear "vapor at a constant pressure". Hope this helps!

[Vivian_Le_1L]

Yes! Both vapor and gas are the same and interchangeable. :)

[Bella Bursulaya 3G]

Vapor and gas are the same thing.

[Tatyana Bonnet 2H]

Vapor and gas are interchangeable. It's like saying water vapor, it is water in the gas phase.

[Charisma Arreola 2F]

Vapor and water are the same phase.

[Zainab Jamali 1H]

I believe vapor refers to when a substance that is commonly liquid/solid is in the gas phase. So in calculations, you would treat gases and vapors the same way!

[Gian Boco 2G]

I think they can be used interchangeably.

[Jaden Joodi 3J]

I'm pretty sure a vapor and a gas are the same thing? After doing a little google search, it seems like there could be a difference. It seems that a vapor is a mixture of a gas and a liquid, where the gas is the main composition.

[Isabella Cortes 2H]

I believe that we use gas and vapor interchangeably for this class

[jasmineculilap_3F]

They're the same thing.

[JaylinWangDis1L]

I believe for this class we can use them interchangeably :)

[Shana Patel 1C]

I thought it was the same thing, and I am assumung that we do not need to know the difference between the two for the class. However I found that vapour phase consists of a phase with two different substances at room temperature, whereas a gas phase consists of a single substance at a defined thermodynamic range, at room temperature.

[Kayla Booker 1F]

I believe they are interchangeable.

[Ethan Goode 2H]

I would think vapor and gas would be the same thing for this class.

[Dane_Beasley_1E]

Vapor and gas are interchangeable terms and are used for the same thing.

[Jose Miguel Conste 3H]

they are the same thing in a concept of things, but I guess vapor is used when water is involved? But that might just be me.

[AndrewNguyen_2H]

They are the same.

[Moura Girgis 1F]

vapor and gas are pretty much the same thing

[Chinmayi Mutyala 3H]

I'm pretty sure they're the same thing.

[Griffin G]

Same thing. If a chemical is usually in a liquid state, one might refer to the gaseous form as a vapor but the definition of both is identical.

[alebenavides]

since they're both the same phase I think its the same thing

[Sukhkiran Kaur 3I]

They're both the same!

[jia207]

I believe the terms vapor and gas can be used interchangeably.

[Susan Chamling 1F]

Hi, I believe they mean basically the same thing for the context of this class.

[Teti Omilana 1G]

Yes, they do mean the same thing.

[Breanna Ouyang 1I]

For the purposes of this class we just assume they are lol

[Namita Shyam 3G]

Yep, I think they basically mean the same thing for this class.

[Muskaan Abdul-Sattar]

I believe for the purposes of this class we can consider their properties and phase the same.

[Dominic Benna 2E]

For this class they are the same for calculations.

[Sukhkiran Kaur 3I]

I think we consider them as the same for chem.

[Vanessa Perez]

they are the same for this class

[DavidTabib 3H]

They are the same thing

[Halle Villalobos 3E]

Hi! Gas and vapor are synonymous.

[James_Hankee_1C]

Vapor and gas are essentially the same things and would both be in a gaseous state.
