1. How much heat is required to raise a 1.00 kg piece of ice at -20⁰C to 70⁰C to make liquid water? 

2. How much heat (in kilojoules) is required to raise a 557.0 g piece of ice at -20⁰C to 110⁰C to make steam?

* NOTE for Question 2, 3: Latent heat of fusion of water is 334 kJ/kg AND latent heat of vaporization of water is2,260 kJ/kg. ALSO, specific heat capacity for water is 4.184 kJ/kg*K, for ice 2.108 kJ/kg*K, and for water vapor (steam) 1.996 kJ/kg*K

 

3. A 15.0 g block of aluminum at in initial temperature of 27.5⁰ C is put in 500. grams of water at 10.0⁰C. What is the final temperature of the block and the water? (The specific heat of Al is 902 J/kg*⁰C and for water is 4.184 kJ/kg*⁰C .)
