what is the difference between evaporation and condensation
Answers
Evaporation is the process in which water is converted into water vapour due to to the heat of the sun's rays.
Condensation is the process in which water turns into water droplets from water vapour due to the loss of heat in the atmosphere.
Answer:
Evaporation Condensation
By definition, evaporation is a process where water changes into vapour. Condensation is the opposite process where water vapour is converted to tiny droplets of water.
Evaporation occurs before a liquid reaches its boiling point. Condensation is a phase change regardless of the temperature.
In terms of molecular movement, when a liquid is heated or when pressure is decreased the forces of attraction between molecules is low. The liquid then evaporates to a gas. When a gas is cooled or when the pressure is increased the forces of attraction between molecules become strong. The gas then condenses to either a liquid or even a solid.
Evaporation can occur in all surfaces, at all times and at all places. Evaporation is frequent when the air is dry, hot and windy. Condensation takes place on salt, hygroscopic nuclei-pollen grains, carbon particles etc.when air temperature is decreased beyond the level of saturation.
Evaporation usually takes place in low altitudes. Condensation happens mainly at higher altitudes.
When evaporation takes place energy is consumed. In the process of condensation energy is released
