8. For water (m.p. 0°C, b.p. 100°C) Heat of fusion = 333 J/g @ 0°C Heat of vaporization = 2260 J/g @ 100°C Specific Heat (solid) = 2.09 J/g°C Specific Heat (liquid) = 4.18 J/g°C Specific Heat (gas) = 2.03 J/g°C Calculate the amount of heat (in kJ) that must be absorbed to convert 54 g of ice at 0°C to water at 70°C. (a) 48.31 (b) 67.54 (c) 37.45 (d) 33.78 (e) 23.67
