If a teaspoon of coffee is placed in a cup of boiling water is it a mixture or a compond?

When a teaspoon of coffee is placed in a cup of boiling water, it creates a mixture. The coffee grounds do not chemically combine with the water; instead, they retain their individual properties while interacting physically. The result is a heterogeneous mixture where the coffee particles are suspended in the water, allowing for extraction of flavors and compounds.
