What is the main reason that evaporation occurs?
What is the main reason that evaporation occurs?
- Air particles collide with the surface of the liquid
- The temperature of the liquid is above the boiling point
- Molecules throughout the liquid gain enough energy to enter the gaseous state
- Molecules at the surface of the liquid gain enough energy to enter the gaseous state (correct)
What is the difference between evaporation and boiling?
What is the difference between evaporation and boiling?
- Evaporation occurs at the surface, while boiling occurs throughout the liquid (correct)
- Evaporation occurs at a lower temperature than boiling
- Evaporation requires more energy than boiling
- Boiling occurs at a constant temperature, while evaporation occurs at a variable temperature
How does temperature affect the rate of evaporation?
How does temperature affect the rate of evaporation?
- The warmer something is, the slower evaporation occurs
- Temperature has no effect on the rate of evaporation
- The rate of evaporation is constant regardless of temperature
- The warmer something is, the faster evaporation occurs, up until the boiling point (correct)
