Conversion of solid to liquid
Conversion of gas to solid
2.
Multiple Choice
1 pts•30 s
Explain why evaporation causes a cooling effect.
Answer choices
High-energy particles absorb heat
High-energy particles escape, lowering average energy
Low-energy particles escape
Heat is released during evaporation
3.
Multiple Choice
1 pts•30 s
Describe the effect of increasing temperature on the rate of evaporation.
Answer choices
Rate of evaporation decreases
Rate of evaporation increases
Rate of evaporation remains unchanged
Evaporation stops
4.
Multiple Choice
1 pts•30 s
Name the factor that increases evaporation when a liquid is exposed to moving air.
Answer choices
Surface area
Wind speed
Humidity
Pressure
5.
Multiple Choice
1 pts•30 s
Clarify how surface area affects the rate of evaporation.
Answer choices
Larger surface area decreases evaporation
Larger surface area increases evaporation
Surface area has no effect
Smaller surface area increases evaporation
6.
Multiple Choice
1 pts•30 s
Point out the effect of high humidity on evaporation.
Answer choices
Increases the rate of evaporation
Decreases the rate of evaporation
Has no effect on evaporation
Stops evaporation completely
7.
Multiple Choice
1 pts•30 s
Indicate why clothes dry faster on a windy day.
Answer choices
Wind decreases the temperature
Wind removes water vapor, increasing evaporation
Wind increases humidity
Wind reduces surface area
8.
Multiple Choice
1 pts•30 s
State the role of latent heat in the process of evaporation.
Answer choices
It reduces the temperature of the liquid
It provides energy to break intermolecular bonds
It increases the density of the liquid
It prevents particles from escaping
9.
Multiple Choice
1 pts•30 s
Describe how the nature of a liquid affects its rate of evaporation.
Answer choices
Liquids with stronger intermolecular forces evaporate faster
Liquids with weaker intermolecular forces evaporate faster
All liquids evaporate at the same rate
Intermolecular forces have no effect
10.
Multiple Choice
1 pts•30 s
Explain why evaporation occurs faster in a shallow container compared to a deep one.
Answer choices
Shallow containers have less humidity
Shallow containers have a larger exposed surface area
Deep containers increase wind speed
Shallow containers reduce temperature
