Problem 44E
In a container of negligible mass, 0.200 kg of ice at an initial temperature of - 40.0o C is mixed with a mass m of water that has an initial temperature of 80.0o C. No heat is lost to the surroundings. If the final temperature of the system is 28.0o C, what is the mass m of the water that was initially at 80.0o C?

Problem 44E
In a container of negligible mass, 0.200 kg of ice at an initial temperature of - 40.0o C is mixed with a mass m of water that has an initial temperature of 80.0o C. No heat is lost to the surroundings. If the final temperature of the system is 28.0o C, what is the mass m of the water that was initially at 80.0o C?
ANSWER:Solution to 44E
Step 1
Mass of ice, mi=0.2kg
Initial temperature of ice=-400C=233.15K
Mass of water =M
Initial temperature of water =800C
Final temperature of system =280C
Cice=2100 J/kg-K
Cwater=4190 J/kg-K
Lf=3.34x105J/kg
