Question
**Factors Affecting Vapor Pressure of Liquids**

The question presented is: "For liquids, which of the factors affect vapor pressure?" The correct factors are indicated with checkmarks. Below are the choices provided, with the factors that affect vapor pressure highlighted:

- [x] surface area
- [ ] volume
- [ ] temperature
- [ ] humidity
- [x] intermolecular forces

### Explanation:
- **Surface Area**: The surface area affects vapor pressure because increased surface area allows more molecules to escape into the vapor phase.
  
- **Intermolecular Forces**: Stronger intermolecular forces (such as hydrogen bonds, dipole-dipole interactions, and van der Waals forces) result in lower vapor pressure because molecules are held together more tightly, making it more difficult for them to escape into the vapor phase.

Factors like **volume** and **humidity** do not directly affect the vapor pressure of a liquid. **Temperature** is not checked in this context, although it is a significant factor, because vapor pressure increases with temperature as more molecules have sufficient kinetic energy to escape the liquid phase.
