Question

which statement best explains evaporation and water vapor?
evaporation only happens when water reaches boiling temperature
evaporation happens at all temperatures but occurs faster in warmer conditions
evaporation only happens in cold temperatures
evaporation cannot produce water vapor

Explanation:

Evaporation is the phase transition of liquid water to water vapor. It occurs at any temperature (not just boiling point) because some water molecules have enough kinetic energy to escape the liquid surface. Warmer temperatures increase molecular motion, speeding up evaporation. The other options are incorrect: evaporation does not require boiling, is not limited to cold temperatures, and directly produces water vapor.

Answer:

B. Evaporation happens at all temperatures but occurs faster in warmer conditions
