In a espresso coffee shop stand they prepare steamed milk by bubbling steam at 140 degrees Celsius through a cup of milk at 30 degrees Celsius, raising the temperature of the milk and its container to 50 degrees Celsius. What mass of steam is required to heat 220 grams (essentially as water) in a cup of mass of 100 grams given the following data? The specific heat of milk is equal to 1kcal/(kg*deg C), the specific heat of the cup = 0.2 kcal/(kg*deg C), the specific heat of steam = 0.48kcal/(kg*deg C), the heat of vaporization of water = 540 kcal/kg, and the boiling point of water is 100 deg celcius.
