Temperature Temperament II (Posted on 2013-04-04) Difficulty: 3 of 5
At a bar, there is a bucket containing ice, some of which has melted. A bartender gets an ice cube weighing 20 grams from the ice bucket and puts it into a perfectly insulated cup containing 100 grams of water at 20 degrees Celsius.

Will the ice cube melt completely? What will be the final temperature of the water in the cup?

Bizarrely, I've just been looking at a related problem. (see 'A Scaled-Down Experiment).

I remember seeing somewhere a rule of thumb that about 4 parts of water at room temperature are needed to melt one of ice.

The solution here would seem to confirm that.
