If 42.0 kJ of heat is added to a 32.0 g sample of liquid methane
under 1 atm of pressure at a temperature of -170 oC,
what are the final state and temperature of the methane once the
system equilibrates? Assume no heat is lost to the surroundings.
The normal boiling point of methane is -161.5 oC. The
specific heats of liquid and gaseous methane are 3.48 and 2.22
J/g-K, respectively.
