The Short Answer
From your answers, it seems like you're looking for [vapor pressure](_URL_2_). When a liquid and gas phase exist together they will form an equilibrium where part of the liquid evaporates until it makes up a certain amount of partial pressure. [For water](_URL_2_) you see at 30°C its vapor pressure is 0.0419 atm. This means around 4% of the total air pressure is created by evaporated water. When the vapor pressure reaches 1 atm, bubbles of 100% water can be formed inside te liquid and the water starts boiling. **ELI5 recap:** there is always some evaporation at the surface, but only the boiling temperature new surfaces (bubbles) can be formed inside the liquid. Also, note that humidity percentages are expressed in terms of vapor pressure. At 40% humidity, that doesn't mean 40% of the air is water, but that means that the partial pressure of water is 40% of its maximal vapor pressure.
