For 8.41, it says The following data were collected for a new compound used in cosmetics: !Hfus" 10.0 kJ·mol$1, !Hvap" 20.0kJ·mol1; heat capacities: 30 J·mol$1 for the solid; 60 J·mol$1 for the liquid; 30 J·mol$1 for the gas. Which heating curve below best matches the data for this compound.

It says that the answer is b.
I thought it would be c as the liquid curve is less steep than the solid and gas curve, showing that you need more heat to raise the temp. In graph b, that curve is more steep. Why is b right?

I'm assuming you're referring to 8.43, not 8.41. And you're correct in saying that the right answer is c; the solutions manual confirms this answer.
