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