Eli5 why water doesn’t go back to liquid ? It need to be 100°C to evaporate but once in the air it is not 100°C anymore so how is it that it stay gaz?

When water changes to gas, its molecules break the intermolecular forces that hold them together as liquid. Thus forming water vapor. Once in the air, the surrounding temperature and pressure are such that they do not have enough energy to condense back into liquid.
But when comes into contact with a surface that is cooler than the surrounding air vapor can condense back into liquid form.
