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.
