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 −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 -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.

    . A certain mass (m) of ice, initially at-5.00°C, is placed into a perfectly insulated container along with a certain mass (n) of steam (initially at 120°C). At equilibrium, there is only liquid water in the container. Write one completely detailed calorimetry equation necessary to solve for the equilibrium temperature of the water. Use symbols only (variables and constant names-no numbers), with all symbols defined (including Q's, AT's, etc.). You do not have to solve this equation or actually calculate...

    Ice at -42 C was warmed to steam at 134 C. How much energy, in calories, was gained to warm 250 g of ice to steam? (get the sign right!) Specific heat H2O(g) = 0.48 cal/gram-C, Specific heat H2O(s) = 0.5 cal/gram-C. Specific heat H2O(l) = 1.0 cal/gram-C. Heat of vaporization H2O = 540 cal/gram, Heat of fusion H2O = 80 cal/gram.
