After application, the paint solidifies and becomes tack-free. Depending on the type of binder, this hardening may be a result of curing (polymerization), evaporation, or even phase change brought about by cooling

Paint is made up of several agents. One of the drying agents evaporate when exposed to the atmosphere. This is why you must keep paint sealed or the air will cause it to dry out.

as the paint is exposed to the air it reacts with it, basically paint is a collection of polymers, they stay unjoined until exposed to air, once the air gets to it they join up solid, or dry for want of a better word.

It doesn't actually dry so much as the liquid evaporates away, leaving behind the solid pigment.

paint contains water. Over time, once the paint has been applied, the water content evaporates
