| Feb 9, 2018 at 13:49 | comment | added | Oray | physically this is not a valid answer. If you freeze the water and pour milk on it, there will be physical reaction between water and milk since their temperature will not be the same: it will freeze some water in the milk or melt some water, depending on the temperatures and densities of two substances.... | |
| Feb 9, 2018 at 11:38 | comment | added | Peter Taylor | @PaulParker, cutting the jugs open is not a reasonable interpretation of emptying them into the barrel. IMO if that's the intended answer then the question should be tagged lateral-thinking and a number of Rubio's comments should be flagged as outdated. | |
| Feb 8, 2018 at 23:10 | comment | added | user45221 | @oerkelens As a chemist I assure you that freezing is not considered to be a chemical change (changing the molecular make up). It's pretty much a purely physical change as it's nearly completely reversible with a change in temperature and/or pressure. Hydrogen bonds are not anything like molecular bonds, they are simply inter-molecular forces. | |
| Feb 7, 2018 at 16:03 | comment | added | Tacroy | Freezing just the water and then pouring milk on it (or vice versa) won't work because you can't separate the two perfectly afterwards - pouring room temperature water on frozen milk will necessarily unfreeze some of the milk. You have to go with @PaulParker's original intended answer to be able to really separate the two afterwards. | |
| Feb 7, 2018 at 15:06 | comment | added | user | (Spoiler) The original intended answer was to freeze both jugs, then cut them open and place both blocks of ice into the barrel. This answer just simplifies that process. | |
| Feb 7, 2018 at 9:33 | comment | added | oerkelens | One could argue that freezing the water (creation of hydrogen bonds between the molecules) changes the "molecular make up" of the water, depending on what one defines as "make up". | |
