General Science / Re: How can heat be stored?
« on: 04/06/2022 20:24:28 »Hi B,Hi,It isn't obvious that there is an answer.
I haven't had any suggestions to my question, what chemical when mixed with water makes it hold more heat?
C
Do you mean something like this
Salt hydrate technology

Your link is a bit of an eyful, for a dyslexic, but the answer is probaly in there somewhere
I searched and found this which sounds like what I remember, but I don't think it was common salt, so maybe different chemicals have different properties?
[ Paint each bottle with flat black enamel on one side and with white enamel on the other, using a paintbrush. Black paint absorbs sunlight, so the black side faces the sun. White inhibits heat transmission, so the white side faces the greenhouse wall.
Fill the bottles with a saturated solution of salt and water. A saturated solution is one in which no more salt will dissolve. Salt raises the boiling point of water, thereby increasing the amount of heat each bottle can retain. ]
