Ice at −12.0 °C and steam at 122 °C are brought together at atmospheric pressure in a perfectly insulated container. After thermal equilibrium is reached, the liquid phase at 46.0 °C is present. Ignoring the container and the equilibrium vapor pressure of the liquid, find the ratio of the mass of steam to the mass of ice. The specific heat capacity of steam is 2020 J/(kg.C°).

Ice at −15°C and steam at 120°C are brought together in a perfectly insulated container. After thermal equilibrium is reached, the liquid phase at 50°C is present. Ignoring the container, find the ratio of the mass of steam to the mass of ice. The specific heat capacity of steam is 0.48 cal/(g·C°) and the specific heat capacity of ice is 0.5 cal/(g·C°).

Ice at -10 degrees C and steam at 130 degrees C are brought together at atmospheric pressure in a perfectly insulated container. After thermal equilibrium is reached, the liquid phase at 50.0 degrees C is present. Ignoring the container and the equilibrium vapor pressure of the liquid at 50 degrees C, find the ratio of the mass of steam to the mass of ice. The specific heat capacity of steam is 2020J/(kg degree C). Explain everything you´ve done.
