Answer:
1. Evaporation:
Evaporation is the process by which a liquid turns into a gas below its boiling point without reaching the boiling point. This process occurs at the surface of the liquid. Evaporation happens due to the random movement of molecules escaping from the liquid phase to the gas phase. The rate of evaporation depends on factors like temperature, surface area, and humidity.
Example of Evaporation: One common example of evaporation is when water droplets on clothes dry out when hung out in the sun. The heat from the sun causes the water molecules on the surface of the clothes to gain enough energy to escape into the air as water vapor.
2. Boiling:
Boiling is the process in which a liquid turns into a gas throughout the liquid, reaching its boiling point. It occurs when the vapor pressure of the liquid equals the atmospheric pressure. Boiling is a more rapid process compared to evaporation and happens at a specific temperature for each substance.
Example of Boiling: A classic example of boiling is when water is heated in a kettle or a pot on a stove. As the water heats up, bubbles form and rise to the surface. The water then converts into steam as the temperature reaches its boiling point of 100 degrees Celsius (212 degrees Fahrenheit) at sea level.
Difference between Evaporation and Boiling:
The main difference between evaporation and boiling lies in the process and temperature at which they occur. Evaporation happens at the surface of the liquid below its boiling point, while boiling occurs throughout the liquid at a specific temperature (boiling point). Furthermore, evaporation is a slow process, whereas boiling is a rapid event.
