The process of paint drying on a fence in the sun involves the evaporation of the volatile solvents in the paint, leaving behind the solid pigment particles that adhere to the surface. As the solvent evaporates, the paint undergoes a chemical reaction known as polymerization, where the molecules cross-link and form a durable film. The exposure to sunlight can accelerate the drying process by providing heat energy to facilitate solvent evaporation and polymerization reactions. Factors such as temperature, humidity, and type of paint can also influence the speed and quality of the drying process.
It is a chemical change. Fermentation causes bonds to break within a compound and new bonds form thus chemically changing the initial 'reactant'.

It is a physical change, because it is still H20 when it evaporates and turns into vapor.
Examples of sun drying include drying fruits such as raisins and apricots, vegetables like tomatoes and peppers, herbs, nuts, and meats. It involves placing the food in direct sunlight to remove moisture and preserve it for long-term storage.
Puddles drying up in the sun are examples of evaporation, where liquid water is converted into water vapor due to exposure to heat and sunlight. This process is a natural part of the water cycle in which water evaporates from the Earth's surface into the atmosphere.

Obviously it is. There are no implications of a chemical change at all. It can easily be reversed, and, it's overall fundamental state remains the same.
Drying (involving only the water evaporation) is a physical change.
Sun drying, one of the oldest known methods of fruit preservation, originated thousands of years ago

Ultraviolet rays of sunlight helps in drying of clothes.
When you do a writeup on sun drying fruits and vegetables be sure to include information on how to prepare them for drying, such as do you peel tomatoes for drying or not, how to avoid insects from getting on you drying screens, and how to store and use them after drying.
Keep them out of the sun
