A substance has a melting point of 20°C and a heat of fusion of 3.9 x 104 J/kg. The boiling point is 150°C and the heat of vaporization is 7.8 × (10) with superscript (4) J/kg at a pressure of 1.0 atm. The specific heats for the solid, liquid, and gaseous phases are 600 J/(kg∙K), 1000 J/(kg∙K), and 400 J/(kg∙K), respectively. The quantity of heat required to raise the temperature of 3.80 kg of the substance from -6°C to 128°C, at a pressure of 1.0 atm, is closest to A. 560 kJ.

B. 770 kJ.

C. 620 kJ.

D. 210 kJ.

E. 470 kJ.
