The time it takes to become cold enough to freeze is pressure-dependent. "Room temperature" can be assumed in the case, or hell, I could have told it it was 21°C. I only wanted a ballpark figure to base a rough plan around ("This will take around this long, so I have this much time before I can do X"), which was certainly within the power of Wolfram Alpha to give me.
The point that this example is trying to illustrate is that Wolfram Alpha is not a search engine ("Find this out for me"), it is a definition engine ("Given these definitions, what is X"), and while it advertises itself as the former with the examples given, doesn't especially succeed at it to any specific degree.
