How does evaporation differ from boiling

Evaporation and boiling are both processes where a liquid turns into a gas (vapor), but they differ in several key ways:

• Location: Evaporation is a surface phenomenon, meaning it only occurs at the surface of the liquid. Boiling is a bulk phenomenon, meaning it happens throughout the entire volume of the liquid, forming bubbles from within.
• Temperature: Evaporation can occur at any temperature below the liquid's boiling point. Boiling occurs only at a specific, constant temperature known as the boiling point (e.g., 100°C for water at standard pressure).
• Rate: Evaporation is typically a slow and silent process. Boiling is a fast, vigorous, and often noisy process.
• Energy Source: Evaporation takes its required energy (latent heat of vaporization) from the immediate surroundings, which is why it causes cooling. Boiling requires a continuous supply of heat from an external source (like a stove) to be sustained.
