Questions and Answers

What is the primary reason for faster evaporation in an area of low pressure?

  • There is less exertion on the surface keeping the molecules from launching themselves (correct)
  • Molecules have less energy to escape
  • Molecules are more densely packed
  • Molecules have a lower boiling point
  • Why does a substance with a larger surface area evaporate faster?

  • Because there are more surface molecules that can escape (correct)
  • Because the density of the substance decreases
  • Because the temperature of the substance increases
  • Because there are fewer molecules at the surface
  • What is the relationship between the density of a substance and its evaporation rate?

  • Density has no effect on evaporation rate
  • Higher density results in faster evaporation
  • Higher density results in slower evaporation (correct)
  • Lower density results in faster evaporation
  • What is the effect of increasing the temperature of a substance on its evaporation rate?
