Unit 1-1.6- Evaporation and condensation Flashcards
1
Q
What is evaporation?
A
When a liquid turns into a gas.
2
Q
Why does evaporation take place?
A
Evaporation occurs because the most energetic liquid molecules escape the surface of the liquid and enter the air.
3
Q
What does this mean for the rest of the liquid?
A
Therefore the average kinetic energy of the molecules is less, so the temperature of the liquid decreases.
4
Q
What does this mean evaporation causes?
A
Cooling.
5
Q
How can you increase the rate of evaporation?
A
Increasing the surface area of the liquid.
Increasing the temperature of the liquid.
Creating a drought of air across the liquids surface.
6
Q
What is condensation?
A
When a gas turns into a liquid?
7
Q
How can you increase the rate of condensation?
A
Increasing the surface area.
Reducing the surface temperature.
