Specific heat capacity of water at different temperatures
Thread Content
+What is the specific heat capacity of water at 5℃? -What is the specific heat capacity of water at 25℃? In which book can I find it?
Look it up in physical chemistry textbooks or chemical solvent manuals
-What is the density of water at 25℃?
Is water still in a liquid state at minus twenty-five degrees?
You definitely don’t seem like someone who works in production! -Water at 25℃ is generally used as a cooling medium in the chemical industry; it is essentially a 37% calcium chloride aqueous solution, which is referred to in the industry as water at -25℃
That’s called a 37% calcium chloride solution; it’s not water anymore
This is industry jargon; indeed, there is a problem with the way it’s expressed. Here we call it chilled water or frozen water. I don’t use a calcium chloride solution, because chloride ions cause severe corrosion. The temperature of the ice water I use isn’t extremely low either; it’s around -10 degrees. So I replaced the calcium chloride aqueous solution with an ethylene glycol aqueous solution. You can give it a try and research it.
