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 are the final state and temperature of the methane once the system equilibrates? Assume no heat is lost to surrounding. The normal boiling point of methane is -161.5°C. The specific heat of liquid and gaseous methane are 3.48 and 2.22 J/g-K, respectively. deltaHvap = 8.20 kJ/mol. Molar mass of CH4 = 16.04 g/mol.

What happens to the temperature of a substance when the average kinetic energy of its particles increases?
