A substance has a melting point of 20°C and a heat of fusion of 3.4 × 104 J/kg. The boiling point is 
and the heat of vaporization is 
at a pressure of one atmosphere. The specific heats for the solid, liquid, and gaseous phases are 600 J/kg ∙ K (solid), 1000 J/kg ∙ K (liquid), and 400 J/kg ∙ K (gaseous). How much heat is required to raise the temperature of 
of this substance from 
to 
at a pressure of one atmosphere?
• 320 kJ
• 92 kJ
• 260 kJ
• 190 kJ
• 230 kJ
