Why do wider cups evaporate faster than thiner ones?

Wider cups evaporate faster than thinner ones because they have a larger surface area exposed to the air, allowing more molecules to escape into the atmosphere. Additionally, the greater surface area facilitates increased heat absorption from the environment, which can further enhance the rate of evaporation. In contrast, thinner cups have a smaller surface area, limiting the number of molecules that can vaporize at any given time.
