Easy# Energy Required for Phase Change

APPH12-W0@RJA

Which of the following phase changes requires more energy added: melting a $5\text{ kg}$ block of ice or boiling a $1\text{ kg}$ mass of water?

Assume the temperature of the ice/water is already at the point for a phase change to occur.

(${ L }_{ f }=3.35\cdot { 10 }^{ 5 } \frac { J }{ kg }; { L }_{ v }=2.26\cdot { 10 }^{ 6 } \frac { J }{ kg }$)
