A 200 gram of ice block falls from a height of 80 meters onto abucket of 1 kg water in a copper bucket of mass 100 grams. Theinitial temperature of the ice is 0 and the bucket and water is 20C. Assume that 60% of the potential energy of the ice block goesinto heat!!!! What is the final temperature of the ice, water andbucket mixture?? If not all the ice melts, then what is the finalmass of the remaining block of ice?
Use Ccu = .092 cal/g.C, Cwater = 1cal/g.C, Lfwater = 333.55 J/gram
answer choices
a) 4.02 C
b) 61.6 grams of ice block left
c) 45.5 grams of ice block left
d) 3.53 C
e) 3.50 C
