The human body obtains 915 $\mathrm{kJ}$ of energy from a candy bar. If this energy were used to vaporize water at $100.0^{\circ} \mathrm{C}$ , how much water (in liters) could be vaporized? (Assume the density of water is 1.00 $\mathrm{g} / \mathrm{mL.}$ .

Key Concepts

Density and Unit Conversion

Density serves as the bridge for converting between mass and volume, enabling the calculation of how much of a substance (by volume) corresponds to a given mass. This is particularly relevant when the problem specifies a density to allow conversion from grams to milliliters or liters.

Energy Conversion

Understanding energy conversion involves translating one form of energy (such as chemical energy from food) into another form (such as thermal energy to vaporize water). It also requires proper unit conversion, for instance from kilojoules to joules, to use in calculations involving the latent heat.

Latent Heat of Vaporization

This concept refers to the amount of energy required to convert a unit mass of a substance from a liquid to a gaseous state at its boiling point without changing its temperature. It is crucial in thermodynamics for calculating the energy needed for phase transitions.
