Does Evaporating KNO3 Solution Release Heat Energy?

AI Thread Summary
When KNO3 solution dissolves, it absorbs heat energy from the environment, and upon evaporation, this heat energy is released. The discussion touches on thermodynamics, particularly the challenge of harnessing heat energy to generate more heat in repeatable processes. Combustion reactions, like burning wood, exemplify this concept, but reversing such reactions poses difficulties. The conversation also highlights the cyclical nature of dissolving and evaporating salts, with a focus on the need for more information on thermodynamic principles and potential users with expertise in this area.

When KNO3 solution dissolves it absorbs heat energy from the environment. So when it evaporates, is this heat energy released?
 
Engineering news on Phys.org
Yes.
 
Ok, know anything about thermodynamics Borek?
 
Enough to be sure about the answer to this question. Not much more, as what I have learned back in eighties mostly evaporated, increasing entropy of the surroundings.
 
I've been trying to broaden my understanding of thermodynamics recently and atm I am exploring the idea of using heat energy to yield more heat energy, in situations where they are easily "repeatable"

Obviously lighting something up like wood etc, is an example of heat energy releasing even more heat energy, but reversing these combustion reactions is difficult.

Once you have the salt back from evaporation, you can dissolve it once again in some water.

I'm having no luck with finding info regarding this on the web. You wouldn't happened to know of a user that would have some understanding of this kind of thing?
