Re: Straight Water for Coolant
my two cents on cooling (though it has been some time since my last
chemistry course ...)
>I'm fairly certain that the second statement is incorrect, the boiling point

I believe that adding salt to water lowers it boiling temperature. So it must
be matter of what you add ...
>The first point though may be entirely correct, and is a seperate issue. How

Specific heat must be high, as well as conductivity,
but I believe that a less viscous fluid would make a better heat dissipator
since it would flow faster. Am I right ?

Isn't this the basis for pressure cookers ?
You raise the pressure so that water boils in lower temp ?
I guess it's just discussion for the discussion ... Time to go home ...
