1) How much heat is required to change 50 g of ice at 0 oC into liquid water at 0 oC? (Answer: 4000 cal) 2) If 350 g of water initially at 25 oC released the amount of heat that you found in Part (1), what would its temperature be afterward? (Answer: 13.58 oC)
3) If you were to combine 50 g of liquid water at 0 oC with 350 g of the water at the temperature you found in Part (2), what would the final temperature of the mixture be?
4) Now, if 50 g of ice at 0 oC is combined with 350 g of water initially at 25 oC, what is the final temperature of the mixture?
5) How much heat is needed to raise the temperature of 350 g of water initially at 25 oC to 100 oC?
6) If the heat absorbed by the water in Part (5) came from the condensation of steam initially at 100 oC, how much steam condensed?
