The enthalpy of vaporization (H_vap) is the amount of energy required to convert a unit mass of a liquid into vapor without a change in temperature. To calculate the mass of liquid boiled by 1 kJ of energy, you can use the formula: mass = energy / H_vap. By dividing the 1 kJ (or 1000 J) of energy by the H_vap value (in J/kg), you can determine the mass of the liquid that can be vaporized. This calculation is crucial in thermodynamics and engineering applications involving phase changes.

How is the fusion used to calculate the energy released when a mass of liquid freezes an endothermic reaction?
Fusion, in the context of freezing, refers to the process of a substance transitioning from a liquid to a solid state. During this phase change, energy is released into the surroundings, which is an exothermic reaction, not endothermic. To calculate the energy released when a mass of liquid freezes, you can use the formula ( Q = m \times L_f ), where ( Q ) is the heat released, ( m ) is the mass of the liquid, and ( L_f ) is the latent heat of fusion for the substance. This calculation quantifies the energy transferred as the liquid solidifies.
