Academics

What is the heat change in J associated with 15 g of solid ethanol at -177 oC changing to gas at 146 oC?

c(ethanol) (g) = 1.22 J/(g.K)

c(ethanol) (liq) = 2.44 J/(g.K)

c(ethanol) (s) = 1.89 J/ (g.K)

?Hfus(ethanol) = 5.01 kJ/mol

?Hvap(ethanol) = 38.6 kJ/mol

The freezing point of ethanol is -114 oC.

The boiling point of ethanol is 79 oC.
