How much heat must be removed from 456 g of water at

25.0^{\circ}\text{C}

to change it into ice at

10.0^{\circ}\text{C}

? The specific heat of ice is

2090 \text{ J/kg} \cdot \text{K}

, the latent heat of fusion of water is

33.5 \times 10^4 \text{ J/kg}

, and the specific heat of water is

4186 \text{ J/kg} \cdot \text{K}

. (a) 105 kJ (b) 153 kJ (c) 57.3 kJ (d) 210 kJ
