Help with a phase change problem please?
If 42.0 kJ of heat is added to a 32.0g sample of liquid methant under 1 atm of pressure at atemperature of -170C, what are the final state and temperatrue of the methane once the system equilibrates? Assume no heat is lost to the surroundings. The normal boiling point of methane is -161.5C. The specific heats of liquid and gaseous methane are 3.48 and 2.22 J/g*K, respectively. Heat of vaporization is 8.20 kJ/mol.
