A 35-G Block of Ice at - 14C14 ^ { \circ } \mathrm { C }

Question 31

Multiple Choice

A 35-g block of ice at - 14C14 ^ { \circ } \mathrm { C } is dropped into a calorimeter (of negligible heat capacity) containing 400 g of water at 0C0 ^ { \circ } \mathrm { C } When the system reaches equilibrium, how much ice is left in the calorimeter? The specific heat of ice is 2090 J/kgK2090 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { K } that of water is 4186 J/kgK4186 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { K } and the latent heat of fusion of water is 33.5×104 J/kg33.5 \times 10 ^ { 4 } \mathrm {~J} / \mathrm { kg }


A) 38 g
B) 41 g
C) 35 g
D) 33 g
E) 32 g
