What is the main cause of evaporation?
What is the main cause of evaporation?
- Molecules throughout the liquid gain enough energy to enter the gaseous state
- The liquid is heated above its boiling point
- Air particles collide with the surface, transferring energy to the liquid molecules
- Molecules at the surface of a liquid gain enough energy to enter the gaseous state (correct)
Which statement about the rate of evaporation is true?
Which statement about the rate of evaporation is true?
- Evaporation occurs faster at lower temperatures
- Evaporation only occurs at the boiling point
- Evaporation rate is unaffected by temperature
- Evaporation occurs faster at higher temperatures (correct)
What happens during the boiling process?
What happens during the boiling process?
- Only surface molecules gain enough energy to enter the gaseous state
- The liquid temperature remains constant until all molecules turn into a gas (correct)
- The liquid temperature continues to rise as more molecules evaporate
- Molecules throughout the liquid gain enough energy to enter the gaseous state
