Text Solution

AI Generated Solution

To determine which liquid has a higher enthalpy of vaporization between acetone and water, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Concept of Enthalpy of Vaporization**: - Enthalpy of vaporization (ΔH_vap) is the amount of heat required to convert one mole of a liquid into vapor at constant temperature and pressure. 2. **Analyzing the Given Information**: ...
