Condensation And Evaporation Flashcards
1
Q
What causes condensation
A
Particles lose kinetic energy so don’t move as quickly. The attractive forces pull them closer together turning it into a liquid
2
Q
What is evaporation
A
When a liquid turns into a gas
3
Q
Particles near the surface of a liquid can escape and become gas particles if :
A
- The particles are travelling in the right direction
2. The particles are travelling fast enough to overcome the attractive forces of the other particles
4
Q
Rate of evaporation increases if:
A
- temperature increases
- Density is lower
- surface area is larger
- airflow over the liquid is greater
5
Q
Why does airflow effect rate of evaporation
A
The quicker the air above the liquid is replaced the lower the concentration of the liquid in the air
6
Q
What increases the rate of condensation
A
- Temperature of the gas is lower
- temperature of the surface area it touches is lower
- density is higher
- airflow is less
