,Vaporization
• Vaporization
is the physical process where a liquid
changes into a gas. It occurs when molecules in a
liquid gain enough energy to overcome
intermolecular forces and enter the vapor (gas)
phase.
,Types of Vaporization:
1. Evaporation
- Occurs at any temperature below boiling point.
- Happens only at the surface of the liquid.
- Slow and natural process.
- Example: Water evaporating from a glass left open.
2. Boiling
- Occurs at a specific temperature (boiling point).
- Happens throughout the liquid.
- Rapid and visible (bubbling).
- Example: Boiling water on a stove.
, 3. Sublimation (special case)
- Solid changes directly to gas, skipping liquid phase.
• - Example:
• Camphor,
• dry ice (solid CO₂).
