Questions and Answers

What is the main difference between evaporation and boiling?

  • Evaporation and boiling both occur throughout the liquid
  • Boiling only occurs at the surface, while evaporation occurs throughout the liquid
  • Evaporation only occurs at the surface, while boiling occurs throughout the liquid (correct)
  • Evaporation and boiling both occur only at the surface
  • Why does evaporation occur faster at higher temperatures?

  • Because air particles collide less with the surface at higher temperatures
  • Because molecules throughout the liquid gain more energy at higher temperatures
  • Because molecules move faster and have more energy at higher temperatures (correct)
  • Because molecules slow down at higher temperatures
  • How does boiling differ from evaporation in terms of temperature?

  • Boiling temperature depends on the type of liquid, while evaporation temperature is fixed
  • Both boiling and evaporation occur at the same temperature
  • Boiling occurs at higher temperatures than evaporation (correct)
  • Boiling occurs at lower temperatures than evaporation
  • Why does a drop of rubbing alcohol evaporate faster on your hand than on a table?
