So if dry air is just low humidity, meaning it has the capacity to hold more water vapour, it should make sense that the water droplets from the clouds will just evaporate and fill that dry air with the evaporated water vapour. Right?
However, why does the dry air cause the water droplets to evaporate in the first place, what provides the water molecules with enough energy to become a gas (water vapour)? Is there an intuitive way to understand this concept without any fancy equations?
From what I have read this process is called entrainment.
In advance, thank you for your answers, I have been trying understand cloud formation and this part really got to me, can't wrap my head around the reason why clouds would dissipate (or partially dissipate) when mixing with dryer air.
