Question

How much heat is required to change 50 g of ice at 0 ^oC into liquid water at 0 ^oC?

Q_{melt ice} =

cal  

2) If 300 g of water initially at 25 ^oC released the amount of heat that you found in Part (1), what would its temperature be afterward?

T_after =

^oC  

3)If you were to combine 50 g of liquid water at 0 ^oC with 300 g of the water at the temperature you found in Part (2), what would the final temperature of the mixture be?

T_final =

^oC  

4)Now, if 50 g of ice at 0 ^oC is combined with 300 g of water initially at 25 ^oC, what is the final temperature of the mixture?

T_final =

^oC  

5)How much heat is needed to raise the temperature of 300 g of water initially at 25 ^oC to 100 ^oC??

Q_{raise water} =

cal  

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?

m_steam =
