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 C, what is the final state of the methane once the system equilibrates? Assume no heat is lost to the surroundings. The normal boiling point of methane is -161.5 C. The specific heats of liquid and gaseous methane are 3.48 and 2.22 J/g.K, respectively.
