Yes, of course it will. You probably already know this. If you leave food uncovered for too long in the fridge, it dries out. If you have never noticed this for yourself, you are too hygienic and well-organized. Loosen up. If you leave ice cubes uncovered in the freezer for a few months, they dry out, leaving limescale. If you have never noticed this for ...
Evaporation depends on vapor pressure of environment. If vapor pressure inside the fridge is lower than saturated pressure of water at $4^\circ C$, then the water will vaporize.
This can happen when water is heated under pressure. If the pressure is sufficient to keep the water liquid at a temperature well above its usual boiling point, and then the pressure is abruptly removed, the water will "flash" into steam all at once, causing what's known as a boiling liquid expanding vapor explosion.
First, let me say that you should not use the formula on engineeringtoolbox. Indeed, you can write $$J=K (c-c_s),$$ where $J$ is the evaporation flux, $c$ the concentration of water vapor in the air and $c_s$ the concentration of saturated water vapor at the given temperature. The problem is that generally, $c$ will not be constant over the position (if ...
If an empty pan is put on the stove and a natural gas flame is placed under the pan, the pan will heat up to the flame temperature of 1083 C. This will probably destroy the pan. On the other hand, if pure water is placed in the pan, the pan will heat up to slightly more than 100 C at sea level, as the heat being put into the pan by the flame boils the ...
