To make ice water, I mix 200 g of water at 25.0 degrees celcius with 100 g of ice cubes at -15.0 degrees celcius. Water density is 1.00 g/cm^3, and the container perfectly insulates the system from the enviroment. Thermal equilibrium is eventually reached. Assume that all the ice must reach 0 degress celcius before any ice begins to melt. (a) determine (i) if any unmelted ice remains, and if so, the mass of the remaining unmeltd ice, and (ii)...
