What is the difference between evaporation and boiling
**Evaporation:**

Evaporation is a physical process in which a liquid changes into a gas at a temperature below its boiling point. It occurs when the molecules of a liquid gain enough energy to escape from the liquid phase and enter the gaseous phase. Evaporation takes place at the surface of the liquid and is a slower process compared to boiling.

**Boiling:**

Boiling, on the other hand, is a rapid vaporization process that occurs when a liquid is heated to its boiling point. It is characterized by the formation of bubbles within the liquid, which rise to the surface and release vapor. Boiling is a more vigorous process than evaporation and requires the input of heat energy.

**Key Differences between Evaporation and Boiling:**

1. **Temperature:** Evaporation occurs at temperatures below the boiling point of a liquid, while boiling occurs at the boiling point.

2. **Speed:** Evaporation is a slow process, occurring at the surface of the liquid, while boiling is a rapid process that affects the entire liquid volume.

3. **Heat Input:** Evaporation can occur without any direct heating, as it relies on the energy from the surroundings. Boiling, however, requires a continuous supply of heat to maintain the boiling process.

4. **Formation of Bubbles:** Evaporation does not involve the formation of bubbles, whereas boiling is characterized by the formation and release of bubbles within the liquid.

5. **Heat Transfer:** During evaporation, heat is absorbed from the surroundings, cooling the liquid and its surroundings. In contrast, during boiling, heat is continuously supplied to the liquid, maintaining its temperature.

6. **Phase Change:** Evaporation is a phase change from liquid to gas only at the surface, while boiling involves a rapid phase change throughout the liquid volume.

**Applications:**

Evaporation is commonly observed in daily life, such as when a wet surface dries or when clothes dry after being hung out to air. Boiling is commonly used for cooking, sterilization, and various industrial processes that require the rapid conversion of liquids into gases.

In conclusion, the key differences between evaporation and boiling lie in the temperature, speed, heat input, formation of bubbles, heat transfer, and phase change characteristics. Evaporation occurs at temperatures below the boiling point, is slower, does not involve bubble formation, and relies on external energy sources. Boiling occurs at the boiling point, is rapid, involves bubble formation, and requires continuous heat input.
