Задача id16324

A thermally insulated vessel contains a mixture of water m1 = 500 g and ice m2 = 500 g at a temperature t = 0 ° C. Dry saturated steam weighing m3 = 80 g at a temperature t2 = 100 ° C is introduced into the vessel. What will the temperature tc be after the thermal balance? Specific heat of vaporization of water r = 2.3 MJ/kg, specific heat of melting of ice L = 0.33 MJ/kg, specific heat capacity of water c = 4.2 kJ/kg K.
