Multiple Choice

How much heat must be added to a 8.0 -kg block of ice at $- 8 ^ { \circ } \mathrm { C }$ to change it to water at $14 ^ { \circ } \mathrm { C } ?$ The
specific heat of ice is $2050 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { C } ^ { \circ }$ the specific heat of water is $4186 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { C } ^ { \circ }$ the latent heat of fusion of ice is 334,000 J/kg, and 1cal=4.186 J.
