A. drinking it cold: Temperature does not significantly influence alcohol absorption. The rate is not increased by consuming cold beverages. B. an empty stomach: Without food, alcohol passes quickly into the small intestine where it is rapidly absorbed into the bloodstream, increasing its effects. C. drinking it warm: Warm temperature may slightly increase vasodilation but does not significantly affect absorption rate compared to stomach contents. D. drinking large amounts: Drinking more increases alcohol concentration but does not increase absorption rate per unit; rather, it may saturate metabolic pathways.
