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

Re: Vapor vs gas
They are the same thing just a different way of saying them. They are both the same phase

Re: Vapor vs gas
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.

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

Re: Vapor vs gas
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).

Re: Vapor vs gas
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.

Re: Vapor vs gas
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!

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

Re: Vapor vs gas
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.

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

Re: Vapor vs gas
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).

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

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

Re: Vapor vs gas
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.

Re: Vapor vs gas
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.

Re: Vapor vs gas
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.

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

Re: Vapor vs gas
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!

Re: Vapor vs gas
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.

Re: Vapor vs gas
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.

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.

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

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

Re: Vapor vs gas
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!

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

Re: Vapor vs gas
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!

Re: Vapor vs gas
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.

Re: Vapor vs gas
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.

Re: Vapor vs gas
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.

Re: Vapor vs gas
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.

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