In an effort to cool a 12- fluid-oz drink in a can, a person grabs the can and starts shaking it in the iced water of the chest at 32°F. Using the properties of water for the drink, determine the mass of ice that will melt by the time the canned drink cools to 37°F. The density and specific heat of water at the average temperature of (85+37)/2 = 61ºF are ρ = 62.3 lbm/ft3 and cp = 1.0 Btu/lbmºF (Table A-3E). The heat of fusion of water is 143.5 Btu/lbm.
