Questions and Answers

What is the main reason that evaporation occurs?

  • Air particles collide with the surface of the liquid
  • The temperature of the liquid is above the boiling point
  • Molecules throughout the liquid gain enough energy to enter the gaseous state
  • Molecules at the surface of the liquid gain enough energy to enter the gaseous state (correct)
  • What is the difference between evaporation and boiling?

  • Evaporation occurs at the surface, while boiling occurs throughout the liquid (correct)
  • Evaporation occurs at a lower temperature than boiling
  • Evaporation requires more energy than boiling
  • Boiling occurs at a constant temperature, while evaporation occurs at a variable temperature
  • How does temperature affect the rate of evaporation?

  • The warmer something is, the slower evaporation occurs
  • Temperature has no effect on the rate of evaporation
  • The rate of evaporation is constant regardless of temperature
  • The warmer something is, the faster evaporation occurs, up until the boiling point (correct)
