Archimedes decides to take a warm bath. If 1 calorie equals 4.187 Joules,
and the heat of fusion of ice/water is 334 J/gram, calculate the number of calories it takes to liquefy a solid block of ice of mass 100 kg at 0°C.
Use scientific notation.

Elena,
Q=λm=334 000 J/kg •100 kg =33400000 J=3.34•10^7J=7977452.9 cal=
