Why aqueous potassium hydroxide leads to the formation of alcohols but alcoholic potassium hydroxide leads to the formation of hydrocarbon?

Aqueous potassium hydroxide can act as a nucleophile, attacking the electrophilic carbon in an alkyl halide to form an alcohol via an SN2 reaction. On the other hand, alcoholic potassium hydroxide serves as a strong base, favoring elimination reactions like E2, which lead to the formation of alkenes or alkynes from alkyl halides.
