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.
