Evaporation and Condensation.

Q8. What happens in evaporation and condensation?
EVAPORATION HAPPENS WHEN A LIQUID IS WARMED UP AND CHANGES TO A VAPOUR.
Particles at the liquid’s surface vibrate so fast they escape altogether. Condensation happens when a vapour is cooled down and becomes liquid. Evaporation and condensation takes place not only at boiling point, but also at much cooler temperature.
