Boiling vs Evaporation (Definition, Examples, & Explanation)

An in-depth look at the differences and similarities between boiling and evaporation. The topic of boiling and evaporation come up frequently in introductory physical science courses. By comparing and contrasting the two ideas you'll develop a fuller understanding. Note that this video focuses on the difference between boiling and evaporation of water (H2O). --Boiling-- • Bubbles form throughout liquid. • Takes place throughout the liquid. • Faster process. • Boils at a specific temp.(boiling point). • Temperature remains constant. • Thermal energy from external source. --Evaporation-- • No bubbles. • Takes place only on surface of liquid. • Slower process. • Occurs at any temperature. • Temperature can fluctuate. • Thermal energy from surroundings. --Similarities-- • Both involve liquids changing to gases. • Both need energy to take place. • Both are physical changes. --Learning Resources-- Introduction to Boiling:    • What is boiling? An Introduction   Boiling & Vapor Pressure:    • Vapor Pressure and Boiling   Boiling & Atmospheric Pressure:    • Atmospheric Pressure and Boiling   More chemistry help at http://www.Breslyn.org .
