Answer 2

Depends on what you want to use the liquid for.  If you want to drink it I suggest Ice.  If not dissolving KCl in it is usually good to make it pretty cold.

Dry ice, solid CO2 undergoes sublimation at -78C which is pretty chilly.  If the liquid is water based then it may very well freeze it.
