2.997 kg of ice at 35 degrees Celsius are thoroughly mixed with 138.6 kg of water at 3.9 degrees Celsius in a wellinsulated container at standard temperature and pressure.
Determine the proportions of ice (if any) and water in the final mixture.
Bonus: what is being simulated?
(In reply to
Solution (w/o bonus) by Kenny M)
The original 'experiment' involves 1.386*10^9 cubic kilometers of water at 3.9 degrees Celsius, and 31.6*10^6 cubic kilometers of ice at an average of 37 Celsius, plus an additional 1.1*10^6 cubic kilometers of ice at 17 Celsius. (These figures differ depending where one looks).
The specific heat of ice (averaged over the range) is 1954.75 joules per kilogram per degree see http://www.engineeringtoolbox.com/icethermalpropertiesd_576.html.
The density of ice is 0.9167 at 0 Celsius, with the density of water assumed to be 1.
