Information about Acetone (C3H6O) :

Boiling Point= 56.1 C

Melting Point= -94.7 C

Heat of Vaporization= 31.3 kj/mol

Heat of Fusion= 5.71 kj/mol

Specific Heat Capacities:

Csolid= 1.60 J/g*K

Cliquid= 2.20 J/g*K

Cgas= 1.30 J/g*K

a) Draw a heating curve that starts at -50 C and goes to +100 C. Take into account that since the specific heats are different, the heating rates will also differ.

b) What is the total energy change of a process in which 18.4 grams of acetone vapor (at 100.0 C) is placed into an empty and sealed container (that cannot expand or contract any), and then the container is cooled until all the acetone solidifies?
