Re: Vapor?

Okay

??

I have been doing heat and such with my physics students.
Everytime I say gas, they bring up vapor.

I don't know where it comes from and I keep trying to get them to stop using vapor

Why?

but it seems stuck in their minds..
Esp. that gas and vapor are the same.

Is this a problem?

There is no physical or chemical difference between a vapor
and a gas. The difference in connotation is subtle and not
very important.
