A $6\mathrm{.}00$ kg piece of solid copper metal at an initial temperature $T$ is placed with $2\mathrm{.}00$ kg of ice that is initially at $-10\mathrm{.}0C.$ The ice is in an insulated container of negligible mass and no heat is exchanged with the surroundings. After thermal equilibrium is reached, there is $0\mathrm{.}90$ kg of ice and $1\mathrm{.}10$ kg of liquid water.
