A 440-G Block of Ice At Ice $- 15.0 ^ { \circ } \mathrm { C }$

question 12

Multiple Choice

A 44.0-g block of ice at $- 15.0 ^ { \circ } \mathrm { C }$ is dropped into a calorimeter (of neglible heat capacity)
containing 100 g of water at $5.0 ^ { \circ } \mathrm { C }$ When equilibrium is reached, how much of the ice will have
melted? The specific heat of ice is $2090 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { K }$ that of water is $4186 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { K }$ and the latent heat of fusion of water is $33.5 \times 10 ^ { 4 } \mathrm {~J} / \mathrm { kg }$
