in a closed container 20 g of steam at 100 deg C is mixed with 150 g of ice at 0 deg C. No heat is lost to the container and the final mixture is all water Cwater =4190 J/Kg/C Cice = 2090 J/Kg/C Csteam = 1996 J/Kg/C . The latent of heat of fusion of water is 3.33 x 10^5 J/Kg and the latent heat of vaporization of water is 22.6 x 10^6 J/Kg   
a. How many changes of state do you need to consider in this problem?
b. what is the final equilibrium temperature of the mixture?
please show all work w b include the formula you are using prior to putting numbers in please
thank you
