A substance has a melting point of 20deg c and a heat of

A substance has a melting point of 20° C and a heat of fusion of 2.9 × 104 J/kg. The boiling point is 150° C and the heat of vaporization is 5.8 × 104 J/kg at a pressure of one atmosphere. The specific heats for the solid, liquid, and gaseous phases are 600, 1000, and 400 J/kg ? K, respectively. The quantity of heat required to raise the temperature of 0.20 kg of the substance from 3°C to 111°C, in kJ, is closest to:
