**Table 11.7: Heats of Vaporization of Several Liquids at Their Boiling Points and at 25°C**

| Liquid           | Chemical Formula | Normal Boiling Point (°C) | ΔHvap (kJ/mol) at Boiling Point | ΔHvap (kJ/mol) at 25°C |
|------------------|------------------|--------------------------|-------------------------------|----------------------|
| Water            | H₂O              | 100                      | 40.7                          | 44.0                  |
| Rubbing alcohol  | (isopropyl alcohol) C₃H₈O | 82.3               | 39.9                          | 45.4                  |
| Acetone          | C₃H₆O            | 56.1                     | 29.1                          | 31.0                  |

**The rate of vaporization increases/decreases with increasing temperature. Explain this phenomenon.**

The rate of vaporization increases with increasing temperature because higher temperatures provide more energy to the molecules, allowing them to overcome intermolecular forces more easily and transition from the liquid to the vapor phase.

**The rate of vaporization increases/decreases with increasing surface area. Explain this phenomenon.**

The rate of vaporization increases with increasing surface area because a larger surface area allows more molecules to escape at the same time, leading to a higher rate of evaporation.

**The rate of vaporization increases with decreasing/increasing intermolecular forces. Explain this phenomenon.**

The rate of vaporization increases with decreasing intermolecular forces because weaker intermolecular forces require less energy for molecules to overcome them and enter the vapor phase. Conversely, stronger intermolecular forces make it more difficult for molecules to escape, reducing the rate of vaporization.
