Chemical that keeps mineral water chilled for long time
Somewhere I heard that people used some kind of chemical which keeps mineral water chilled for long time.
Does anybody knows about such chemical?

Ramani AswathThis does not gel thermodynamically. The time for which some thing remains chill depends on its thermal mass and the heat influx. One cannot use too much quantity of chemicals in some thing meant for drinking.
Since we cannot control heat influx with a chemical and the thermal mass does not change much, it is not possible to keep water chill longer with a chemical in my opinion. -

Sir, I have seen those guys who supplies mineral water locally they are used to drop just one drop of such chemical and that chemical makes water chilled.A.V.RamaniThis does not gel thermodynamically.

If it were true you can use it to prevent premature setting of concrete and give you more working time.
Unfortunately the laws of thermodynamics still apply.

Can i get that chemical's name?

Why don’t CEans do some very basic thermal calculations? They will then know that this is theoretically impossible.
