When bottled water is left in the sun, the heat can cause the plastic bottle to leach harmful chemicals, such as bisphenol A (BPA) and antimony, into the water. Additionally, prolonged exposure to sunlight can promote the growth of bacteria if the water is not properly sealed. It's best to store bottled water in a cool, dark place to maintain its safety and quality.
Entropy increases.
The water evaprates
Water is transformed in vapors.
When you put sugar in water and leave it in the sun, the heat from the sun can increase the water temperature, which helps dissolve the sugar more quickly. As the sugar dissolves, it creates a sugar solution. If left for an extended period, especially in warm conditions, some of the water may evaporate, potentially leading to a more concentrated sugar solution or even crystallization if the conditions are right.
After some time whole water is evaporated.
no, nothing happens to the chemistry of the water. it still stays 2 pars oxygen 1 part hydrogen
After some time whole water is evaporated.
Entropy increases.
When left in the sun, the water in a cup will gradually heat up and may reach a higher temperature than its surroundings. Some of the water will evaporate, turning into water vapor and escaping into the air.

The water will eventually evaporate off and leave the salt, which you can reclaim.
A penny left in the sun will become warmer than its surroundings, and will eventually be picked up by a passerby and carried off.
A chocolate bar left in the sun will melt unless ambient temperature is very cold.
