a bottle of liquid acetone is converted to a gas at 75.0 C. if 628 J are required to raise the temperature of the liquid to the
boiling point, 15.600 kJ are required to evaporate the liquid, and 712 J are required to raise the final temperature to 75.0 C, what is the total energy required for the conversion?
2) evaporate the liquid at 75.0°C 15.6 KJ = 15,600 J
3) raise the temperature to ? 712 J
Total energy: 628 J + 15,600 J + 712 J = 16,940 J
As you must have realized the clue to do the problem correctly is to convert all the energy values to joules, because you cant not add up joules with kilo joules.
