Which chemical chills water?
I have have heard that chilled water bottle dispenser just immerse a thin wooden stick preimmersed in a chemical to chill the water.
Which chemical it could be?Which Chemical chills water? We are used to use chilled water served in opaque plastic bottle at a throw away price.
Certain salts like ammonium nitrate can cool water on dissolution. Not much though. One certainly cannot drink that. Water has a very high heat capacity. To cool one litre water from 30 deg C to 10 deg C one needs to remove 20 kcalories of heat. That is a fair amount of cooling.
For heavens sake please do not try to chill drinking water by dissolving a chemical in it, unless you have a good hospital easy to access.
