Our air conditioner has broken so i was bored and started thinken about something. I calculated that a 10 pound bag of ice will cool my room (which i figured is about 4500 ft^3... yah... i love my room lol) from about 86 freaken degrees!! to about 72 degrees fahrenheit. In my calculations i used the specific heat of dry air by the way :-/... but this is more of a excercise then hoping for a real world solution. Anyhow, does that 14 degree drop seem reasonable?? Not looking for an exact figure or anything because i know theres too many things going on for that that i couldnt account for... just wondering if it sounds reasonable.
