(15 points) An ice cube of mass 0.0340 kg and temperature -10.00 °C is placed in the steam room at a gym. The steam room, which is quite large, is filled with 2.000 kg of steam at a temperature of 110.0 °C (a) (5 points) How much ice is present, and at what temperature, when the ice and steam reach thermal equilibrium? Your answer should be two numbers (b) (5 points) How much water is present, and at what temperature,...

How much heat is required to melt 4.30 kg of ice with an initial temperature of 0 degC, and turn it into steam at 100 degC?
We have a closed system with an aluminum cup, water and a cube of ice. The glass has a mass of 100 grams. The temperature of the glass and water is 20 degrees C. We also have 200 grams of water in total. The cube of ice weighs 5 grams and is at 0 degrees C. Find the equilibrium temperature of the system.
How much heat is evolved in converting 1.00 mol of steam at 160.0 ∘C to ice at -50.0 ∘C? The heat capacity of steam is 2.01 J/(g⋅∘C) and of ice is 2.09 J/(g⋅∘C). Express your answer in units of kilojoules Assume the system is at atmospheric pressure.
