Question
The human body obtains 915 kJ of energy from a candy bar. If this energy were used to vaporize water at 100 C, how much water (in liters) could be vaporized? (Assume the density of water is 1.00 g>mL.)
Step 1
We need to convert this energy into joules because the heat of vaporization for water is given in joules per gram. We know that 1 kJ = 1000 J, so we multiply 915 kJ by 1000 to get 915,000 J. Show more…
