An open jar of coffee undergoes diffusion because the aromatic compounds and volatile oils in the coffee beans are released into the air, creating a concentration gradient. This process allows the scent of coffee to spread and permeate the surrounding environment. As molecules move from an area of higher concentration (inside the jar) to lower concentration (the surrounding air), the aroma becomes noticeable, exemplifying diffusion in action.
