There is a calorimeter composed of a thermally insulated container. Inside it are 1.2 kg of ice at −15 ∘C. How much mass of water at 60 ∘C needs to be added in the calorimeter for the final temperature to be 5 ∘C? If water vapor were introduced at 100 ∘C instead of water, how much mass of steam would have to be added for the final temperature to be 30 ∘C? What volume would the water vapor in the previous part occupy (before adding it to the calorimeter) if the pressure at which it is contained is 1.20 × 105 Pa? NOTE: The molar mass of water is 18 g / mol. ice = 2090 J / kg ∘C. water = 4180 J / kg ∘C. Lf, water = 3.33 × 105 J / kg. Lv, water = 2.26 × 106 J / kg
