42) Evaporation is a cooling process because

1. heat is radiated away
2. of conduction only
3. of conduction and convection
4. the remaining liquid undergoes a decrease in temperature
5. more energetic molecules evaporate, leaving less energetic ones behind

During evaporation the remaining liquid undergoes a decrease in temperature, but it does so because the more energetic molecules will leave and lets the less energetic ones stay.
