Question

both of the process of evaporation and boiling involves the change of state from liquid to gas but still they are different from each other

Answer 1

Boiling is vaporisation of liquid into gas due to continuous heating. Most of the time it is not a natural process.Evaporation on the other hand is a natural process and it is similar to boiling , but the liquid form changes into gaseous form when there is a increase in either temperature or pressure or both.OccurranceLarge massonly on surfaceAmount temperature involvedBoiling happens when the temperature reaches to the boiling point.In Evaporation the temperature does not need to reach to boiling pointBubble FormationBubble formation is visibleBubbles do not form in evaporationEnergyUsually external source of energy is needed for boiling to happen.Most of the time energy for evaporation is supplied by the atmosphere or surrounding. Length of the process Rapid Process Slow process compared to boiling
