What will evaporate faster Dr Pepper Sprite or Gingerale?

The rate of evaporation depends on several factors such as temperature humidity and air flow but generally speaking Dr. Pepper will evaporate the slowest followed by Sprite and then Gingerale.

This is because Dr. Pepper contains the most sugar which acts as a humectant attracting and retaining water molecules Sprite contains less sugar than Dr. Pepper making it more prone to evaporation and Gingerale contains the least amount of sugar so it will evaporate the fastest.
