specific heat

[spdfreek0o]

something im working on for school: is it safe to say that as specific heat increases so does the specific heat of vaporization? And is the relationship pretty linear?

Yeah, I'm pretty sure it's a direct relationship, so I think that as one increases, the other does as well. I just did a quick google search, and if I read correctly, I'm pretty sure that's right. There are some really good chemistry sites out there that we used in AP Chem last year, so just search around and you should be alright.

yeah I'm 95% sure that it is a direct linear relationship, although its been about a year since i've had a chemistry class

No, the heat stays constant until the change is completed.
After the change is completed then heat must be added to go from one stage to another or substance to another.

Like i knew that off the top of my head.

I could be wrong because I failed chemistry and took Physical Science instead !

heat doesn't necesarily need to be added for a phase change. Heat is released from most substances when changing from Solid=>liquid=>gas. Or even solid=>gas.

specific heat doesn't increase... its a constant, liquid water is 1cal/gram*C
ice is .51 water vapor is .48 (http://www.rwc.uc.edu/koehler/biophys/8c.html)

If you're talking generally, then I think you might be right. The specific heat of water is much higher than ice, and you can see that it takes a lot less energy to melt ice than it does to boil water.

^^ same site i used power of google.

same site with some extra elaboration, I loved chemistry in high school.

man i hate chem only because of my teacher, but what dan said is right.
