Задача id9589

The calorimeter at temperature t1 = O°C contained mw = 500 g of water and ml = 100 g of ice. How much water vapor at a temperature t2 = 100 °C was introduced into the water if, as a result, all the ice melted and the temperature in the calorimeter reached t = 90 °C? Heat capacity of the calorimeter C = 1600 J/K, specific heat of vaporization of water r = 2.26 • 106 J/kg, specific heat of melting of ice λ = 3.3 • 105 J/kg, specific heat of water c = 4.19 • 103 J /(kg • K). Neglect energy losses to the environment.
