A 2-kg block of ice with an initial temperature of -20F is dropped into an insulated tank containing 10-kg of liquid water at an initial temperature of 70F. The specific heat of the solid ice is 0.477 Btu/(lbm*F), and the specific heat of the liquid water is 1.00 Btu/(lbm*F). The heat of melting for water is 155 Btu/lbm. Assum that all of these quantities are independent of temperature.
a) Determine the final phase of the water in the tank.b) Calculate the final temperature (F) of the water in the tank.
