A vessel containing a mass mв = 2 kg of water and a mass mл = 0.5 kg of ice at t0 = 0°С was filled with water vapor having a temperature tп = 150°С (at normal pressure). After the ice melted, the temperature in the vessel reached Q = 30°C. What mass of steam is released into the water if the heat capacity of the vessel is Cc = 630 J/K? Specific heat capacity of water sv = 4.19 kJ/(kg K), steam cn = 1.97 kJ/(kg K); specific heat of melting of ice L = 0.33 MJ/kg; specific heat of vaporization r = 2.26 MJ/kg.
